Please read this post even if you have signed up before!

After reading this post, please look at the tag set to see what fandoms are available this year, and make a shortlist of what you plan to offer and request. (The same fandoms can be on both lists, if you want.)

Then sign up at the collection. We recommend you allow at least half an hour to sign up. While you can edit your sign-up over the next week, you will not be able to make any changes after sign-ups close at 9pm UTC 24 October.

If you would like to avoid matching to up to three other participants, with limitations discussed here, you may do so by filling out a Google Form from a link within the AO3 form. If you want to use this feature but cannot use Google Forms, please email the mods. Do Not Match requests will close at the same time as signups.

Requests

• You can request 3-8 fandoms


• Each fandom must be different


• You can request 0*-4 characters in each fandom


• *Requesting 0 characters means "I am happy to receive any nominated character for this fandom. My author gets to choose which one(s)". That includes Worldbuilding for fandoms where Worldbuilding is nominated as a character tag. If no characters are nominated for the fandom, requesting 0 characters means “I am happy to receive any character or worldbuilding for this fandom.”


• "AND" matching means your writer must include every character you select. If you are happy with a subset of your selected characters, indicate this with Additional Tags, and clarify any exceptions in your optional details.


• You can only request characters from the tag set, though your optional prompts may mention other characters to appear too.


• In some fandoms, you can request Worldbuilding as a character. You can find guidance on that here.

AND matching and additional tags
Generally, when you select characters in your sign-up form, it means you want and expect your gift to include all of those characters. This is a key principle for matching and assignments. However, some people like to give their author further options. We are using the Additional Tags section of the form for this.

If you requested 0 characters, or you want all the characters you selected to appear, you will tick the first Additional Tag option, which says "My gift must feature all of my chosen character tags (if 0: any from tag set)". If you think your situation might be different, please read last year’s post about additional tags and select additional tags that are right for your requests. This information is also in the sign-up form.


Optional Details and Do Not Wants (DNWs)
"Optional details" = prompts, ideas, likes, explanations of how you see the canon. Optional details and DNWs can be recorded in the main text section of your requests.

Optional details are optional (ODAO)! Your writer doesn't have to follow your prompts, though they must avoid your DNWs. You don't have to give prompts here, either - though prompts and ideas may be a more inspiring first impression than a list of DNWs on its own. Prompts may be particularly useful if you are requesting a Worldbuilding tag.

See this 2020 post for some considerations when writing your DNWs. Last year, we also clarified our rules and guidance about DNWs.

The Optional Details section of your AO3 requests is especially relevant if you have selected option two of the additional tags, "My gift must feature all of my chosen character tags; or it may use exceptions I explain in the form". In that case, please use this section of the form for explaining how and when your writer is allowed to leave out some of the characters you selected.

Please use minimal html in the optional details field. No images, please.

Please also note in the form if you're able to receive treats - or if you don't want them! Yuletide has a long-established culture of extra gifts, but if you created your account recently, you may have extra gifts turned off by default. Please check your AO3 preferences, and then state in your sign-up form whether you do or do not accept treats.


Letters
You can write prompts and preferences in another space, such as Dreamwidth, Livejournal, Google Docs, or Tumblr, and put a link in your sign-up. This is known as a "letter". Some people write letters; some don't. DNWs and character subsets that are listed in a letter but not in the Optional Details AO3 textbox cause confusion and difficulty for creators, and will not be enforced by the mods. Otherwise, your letter is an extension of your optional details and is treated the same way.

Important: You cannot add a letter after sign-ups close.

Offers

• You can offer 4-10 fandoms


• Each fandom must be different


• You can offer 2-20 specific characters in each


• If you want to offer a fandom that has 0-1 characters available, tick the "Any" box


• If you are willing to write any combination of nominated characters, including Worldbuilding for fandoms where it is nominated, tick the "Any" box


• "Worldbuilding" can also be selected as a character for many fandoms. Please check here to see how we're using it.


• Offers are secret! Please don't declare openly what you're offering.

If you have several fandoms in which you want to offer to write Any nominated characters, you can make your last offer a "Bucket Offer". You can read about bucket offers in the Sign-ups section of the AO3 FAQ. This older tutorial has pictures!

Signing up!

The sign-up form is here.

• Signups will remain open - and editable - until 9pm UTC 24 October.


• You may only sign up to Yuletide with one AO3 account. You must be aged 18 or over to sign up.


• You can find more sign-up information at the Yuletide 2025 FAQ


• There is also specific guidance about how to use Additional Tags

Please check the tag set or the app when signing up. The autocomplete drop-down list in the sign-up form may not show all available characters. If they're in the tag set, you can enter them manually.

Sign-Up Summary

The list of requested/offered fandoms will be available after five people have signed up. Bucket offers do not show up in the list. Checking the sign-up summary for people you may be able to write for is a good idea - although many people sign up at the last minute. The sign-up summary says it updates hourly; in practice it may update less frequently.

Fandoms at 1-1 on the sign-up summary may mean that the same person is offering and requesting the fandom, not that there is a match.

Welcome to Yuletide!

Feel free to ask us questions.

Tag set housekeeping

• We've removed Mouthwashing (Video Game) as that was approved in error. Sorry for getting your hopes up, nominator!


• 烏は主を選ばない | Karasu wa Aruji wo Erabanai | Yatagarasu: The Raven Does Not Choose Its Master (Anime): It’s come to our attention that Nazukihiko and Wakamiya are the same person, so we’re merging those characters.


• Nominator of Luca (The History of Sound) - it looks like the Wikipedia page for this movie incorrectly listed Luca as the name of Lionel's lover in Rome; according to IMDB and the original stories this movie is based on, it's Vincent (who was also nominated), so we're deleting Luca.

Thank you for all the tag set issues you’ve let us know about so far! Please continue to check the tag set and let us know of further corrections we should make. Please tell us about these corrections before 9am UTC, Monday 13 October, so we can fix them before sign-ups.

Limited Do-Not-Match option

Most of the time, the person assigned to create for you in an AO3-based gift exchange, and the person assigned to receive a gift from you, are determined by the tags you select in the sign-up form.

Some exchange moderators also offer participants the option to say "Please do not match me up with [ExampleUserName] or [ExampleUserName2]. I don't want to receive a gift from them or create for them." This feature makes it easier, for example, to offer a fandom requested by six different people including someone you'd prefer to avoid, and have peace of mind that you can still avoid that person.

A Do-Not-Match option is difficult to offer flexibly in Yuletide because of the large number of participants and the large number of people who have only one possible creator or recipient. However, we see a Do-Not-Match option as a valuable tool to reduce friction and make everyone happier, so we intend to offer a limited version of this feature in Yuletide, on a trial basis. Please note that this is not an absolute guarantee you won’t receive a story from one of the people you list.

How it will work

When you sign up on AO3, the sign-up form will also link out to a Google form where you can list the AO3 names of up to 3 people you do not want to match to and can tell us if you want to avoid writing for a person, receiving an assigned gift from a person, or both. We will also ask for those people's AO3 ID numbers, which you can find on their AO3 profiles, and for the email associated with your AO3 name. We will not ask for the reason you wish to avoid a person.

After we run the matching process, we will check all matches against our master Do-Not-Match list. We will take the following actions:

• If your assigned recipient or creator is someone you asked to avoid, we will attempt to match you to someone else.


• If your only possible recipient is someone you asked to avoid, we will email you to recommend you expand your offers. However, we will leave the match in place if you do not respond in the first 24 hours following the close of sign-ups.


• If your only possible creator is someone you asked to avoid, we will send out your requests with initial pinch hits.


• If you are the only possible recipient for a creator you asked to avoid, we will leave the match in place, but will prioritize your requests for double-assignment to two creators. [Because of how matching works, there will always be Yuletide participants who start out with two assigned creators; generally we try to choose them at random.]

We will not take the following actions:

• We will not ask a creator to drop out or expand their offers if their only possible recipient is someone who would prefer to avoid them.


• We will not inform a participant that someone else has asked not to match to them. [This information will be restricted only to the core Yuletide mods, Isis, Morbane, and pendrecarc, and will not be shared with the larger pool of Yuletide assistants.]


• We will not review treats for unwanted matches. Putting someone on your Do-Not-Match list will not prevent them from creating a treat for you (but please see FAQs below for other tools to achieve this).


• We will not prevent someone on your Do-Not-Match list from claiming you as a pinch hit. We will check our master Do-Not-Match list when assigning pinch hits, so if the first person to claim you is a person you prefer to avoid, we will leave a short amount of time to see if another claim comes in. But we will not hold your pinch hit indefinitely or tell the first creator they aren't allowed to claim you.


• We will not ask you why you wish to avoid a particular match.

FAQs (foreseeable/anticipated questions)

Who am I allowed to put on my Do-Not-Match list?
Any three AO3 accounts you would prefer to avoid matching to. This can be for any reason, serious or unserious. Do not tell us the reason, please. If the reason is harassment or similar, we recommend reaching out to the Policy & Abuse team separately. You may only give specific names, rather than a description like "anyone who mostly wants porn".

Can't I just block people I don't want to match to?
No. Adding other users to your block list stops them from giving you a treat (see item AO3-6502 on this news post). It also stops them from being able to comment on your work. However, it does not affect challenge matching. A person you have blocked can be assigned to create for you, and you can be assigned to create for them.

Wait, am I allowed to block people in Yuletide?
Yes. Feel free to use the blocking feature to improve your AO3 experience. However, blocking someone and also matching to them could lead to unhappiness for both of you - so please consider using all the tools at your disposal to avoid matching to people you have blocked. This could mean choosing not to offer a fandom if you suspect it has been requested by a person you wish to avoid, or it could mean using the Do-Not-Match option for people you have blocked.

What other AO3 tools exist to manage my gift experience?
If you wish, you can choose to receive gifts only from assigned writers in a gift exchange or people who have claimed your prompts in a prompt meme. This is sometimes described as turning treats on and off. If you created your account after February 2022, please review this setting in your AO3 account preferences. If you select the setting "Allow anyone to gift me works", you can receive treats. If you do not select this setting, only an assigned author can give you a gift in Yuletide.

Will this be a feature of Yuletide going forward?
Maybe, maybe not. It will depend on how well it works out this year!

Fixes and Polishing

We're ready to work on corrections. Please tell us what we need to fix! We may make posts with further queries, depending on the issues you raise. Please keep an eye out for those! Sign-ups are projected to start October 14. If nothing's wrong in your fandoms - or if you can multitask - take part in activity at yuletide!

If your fandom is the wrong category. (such as Books when it should be Celebrities & RPF - etc.)...

• first, please check if it is also in the right category. If it is also in the right category, we can't help.


• If it's only in the wrong category, please tell us what it is and what category it should be in.

(Please note that if it's a canonical fandom on AO3, we can't change it in the Yuletide tagset - however, we can notify the wranglers of the issue.)

Tell us about…

• if you nominated something, but you can't find it at all


• if you nominated characters in a particular fandom, but you can't find them there


• if the fandom or characters you nominated were changed to something incorrect


• if you see the exact same character tag (including disambiguation) in multiple fandoms


• if a character or fandom name is mis-spelled (we don't care as much about disambiguations, so if the words in brackets entered after your fandom name are wrong (mis-spelled, misleading), feel free to tell us, but this may not be corrected.)


• if you see something that doesn't belong


• if you see two fandoms that are duplicates of each other


• if you see the same character twice under one fandom


• if your new fandom has been categorized in the wrong media category (and it isn't in any other category).

For missing nominations and corrections to your nominations, please provide your nominations link.

DO NOT tell us:

• if your fandom is in the wrong media category (a book under movies, etc), unless that is the only category that it is in. Please check ALL the categories before you report a problem.


• if your fandom is in Uncategorized Fandoms. This is a work in progress, please be patient as we work through these fandoms.


• if the characters in your fandom all belong, but the disambiguation tags entered in brackets after their names aren't all the same. Sometimes we have to enter really long strings after a character name to keep the character where they're supposed to be. We only care if the information in brackets is wrong.

Some Stats

This year, we approved 16,466 characters across 4,278 fandoms!

The most nominated fandom this year was Murderbot (TV), with 15 nominators. Close behind it was Clair Obscur: Expedition 33 (Video Game), with 13 nominators.

Nine Worlds Series - Victoria Goddard is far in the lead by approved characters for a second year in a row, with 39 to select from. Lymond Chronicles - Dorothy Dunnett has 30, and The Goblin Emperor Series - Katherine Addison is in third with 27.

At the other end of the spectrum, 82 fandoms were nominated without characters.

Worldbuilding was nominated 356 times this year! John edged out Jack for the most common first name. Our review suggests the most ubiquitous characters of 2025 are, once again, Dracula and Sherlock Holmes.
