2025 sign-ups are open at AO3!

The basics

• You need an AO3 account. You can request an invite here, or contact the mod directly.


• One sign-up only per person.


• If there are things that would ruin a gift for you, please enter them in the sign-up form, in the "Do-Not-Wants and Optional Details" field, as Do Not Wants or DNWs.


• You can write prompts, if you want, but you don't have to. You can link to a longer document, a "letter", with more information about your prompts and preferences, if you want, but you don't have to. Letter links can't be added after sign-ups end. If writing a letter, please try to complete it by the time assignments go out. The preferences in your optional details can include characters and relationships, but your creator isn't bound by them - please do not request fandoms where you are only interested in a very small subset of the characters or the worldbuilding.


• You can organize your requests according to whether you'd like art or fic or both, and crossovers or fusions or both. Each request and offer must include at least one of the tags Art/Fusion, Fic/Fusion, Art/Crossover, and Fic/Crossover. Crossovers and fusions are defined at the collection.


• You must sign up with 3 (min) to 10 (max) requests, and 1 (min) to 10 (max) offers.


• Not everyone can receive treats, so please note in your optional details if treats are welcome or if you have disabled them.


• You can use the "Notes to Mod" field to tell me more about your matching preferences, or you can leave that blank. You can ask to avoid other people ("Do Not Match" requests). Please don't tell me why you wish to avoid any person. Please do tell me whether you would prefer not to receive a pinch hit or treat from a person you don't want to match with. I can't honour all preferences; if I need to read someone's optional details or Do-Not-Wants to figure out if they're compatible with your matching preferences, that's too specific, sorry. If you have blocked any other participants, you can still be assigned to receive from or create for them, so consider asking not to match to them.

How to combine fandoms, and making sure you have enough combinations

• Each of your requests and offers needs to include 2-10 fandom tags from the tag set.


• Your requests (in total) must include at least 5 different fandom tags.


• Your requests (in total) must include at least 5 different fandom combinations. (That is: Harry Potter and John Wick is one combination. A request for Harry Potter, Buffy the Vampire Slayer, and John Wick includes 3 different fandom combinations: HPxB, BxJW, HPxJW.)


• Your combinations cannot all require knowledge of your one favourite fandom. Ie, the five requests AxB, AxC, AxD, AxE, and AxF would all require your creator to know fandom A. You would need at least one other request that doesn't include fandom A.


• Don't put fandoms into the same request or offer if you aren't interested in all the combinations they could make. For example, if you want Harry Potter and Buffy, and also Harry Potter and John Wick, but you don't want Buffy and John Wick, putting those three in the same request would be a bad idea because your creator could have offered Buffy and John Wick but not Harry Potter. In that case, put John Wick and Buffy in two different request slots and put Harry Potter in both.


• Don't put fandoms into the same request if the combination they make wouldn't create a fusion or crossover. Examples:
  • Don't put Tamora Pierce's Protector of the Small quartet in the same request as the Lioness quartet - these are subseries of the same world with shared characters and settings
  
  
  • Don't put Captain America movies in the same request as Marvel Cinematic Universe, since the Captain America movies are a subset of the Marvel Cinematic Universe
  
  
  • Don't put Mo Dao Zu Shi in the same request as The Untamed, since one is an adaptation of the other
  
  
  • It's fine to combine similar fandoms in this way in your offers, just not in requests.

"Any Other Fandom" tags

This is a BONUS wildcard system that may make it easier for you to cover all the fandom combinations you are interested in receiving. It is an optional extra: ignore it completely if you want. If you aren't interested, just don't select the "Any Other Fandom" tags.

If interested, here's how it works.

-In one of your requests, select a fandom from the tagset and "Any Other Fandom I've Requested in CW2025". This means that your creator can combine that fandom with any fandom you've ticked in any of your other requests.

-Or, in one of your requests, select "Any Other Fandom I've Requested in CW2025" and "Any Other Fandom I've Requested in CW2025 (Select Only In Combo With AOF Tag & No Other Fandoms)". This is using tags to say "Absolutely any possible 2-fandom combination is welcome as long as both fandoms appear somewhere in my requests this year".

Some examples

Normal sign-up
Request 1: Fic/Crossover, Murderbot (TV), Vorkosigan Saga - Lois McMaster Bujold, All For The Game - Nora Sakavic, Babylon 5 (T)
Request 2: Art/Fusion, Fic/Fusion: Horus Heresy - Various Authors, Black Jewels
Request 3: Art/Fusion, Chronicles of Narnia, Revolutionary Girl Utena, Our Flag Means Death (TV)
Request 4: Fic/Fusion: Chronicles of Narnia, Moby Dick
Request 5: Fic/Fusion: Chronicles of Narnia, Psmith - P. G. Wodehouse,

Here I could get a crossover between Babylon 5 and Vorkosigan Saga, but if I got a fusion between Black Jewels and All for the Game, it would not fulfil my request.

This set-up also means that I am prompting for multiple fusions with the Chronicles of Narnia. Keeping requests 3, 4, and 5 separate is different to putting all of these fandoms in the same request - if I did that, I might get Moby Dick and Our Flag Means Death. (No shade or judgment if you think that would be great! This is purely an example.)

Using Any Other Fandom tags
Request 1: Fic/Crossover, Buffy the Vampire Slayer, Dark Lords of Derkholm, The Old Guard
Request 2: Art/Fusion, Fic/Fusion: Dragonriders of Pern, The Hunger Games, Black Jewels
Request 3: Art/Fusion, Chronicles of Narnia, Revolutionary Girl Utena
Request 4: Fic/Fusion: Chess (Musical), Any Other Fandom I've Requested in CW2025

This could save time because if a creator likes the musical Chess, they can combine that with any other fandom in the requests. (Only by writing a fic fusion, though).


Using Any Other Fandom tags - both of them
Request 1: Fic/Crossover, Buffy the Vampire Slayer, Dark Lords of Derkholm, The Old Guard, Chess (Musical)
Request 2: Art/Fusion, Fic/Fusion: Dragonriders of Pern, The Hunger Games, Black Jewels
Request 3: Art/Fusion, Chronicles of Narnia, Revolutionary Girl Utena
Request 4: Fic/Fusion: Any Other Fandom I've Requested in CW2025, Any Other Fandom I've Requested in CW2025 (Select Only In Combo With AOF Tag & No Other Fandoms)

In this case, Request 4 means I could get a fusion story between Utena and the Old Guard, Black Jewels and Narnia, or Chess (Musical) and Pern. Anything's fair game. No combination is excluded.


This is the only way "Any Other Fandom I've Requested in CW2025 (Select Only In Combo With AOF Tag & No Other Fandoms)" should be selected in your requests. It should appear as the second fandom with "Any Other Fandom I've Requested in CW2025" as the first fandom, and there should not be a third fandom in that request.

If using "Any Other Fandom I've Requested in CW2025", please list out what those fandoms are in the optional details of the request where you have selected this tag. This helps creators check they're combining the right fandoms.

Please feel free to ask if you have questions!

More tag set notes
When looking through the tag set, please keep in mind the Uncategorized fandoms in the tag set. Some of these may be fandoms you've never heard of - but some of them may just be sub-groupings of a fandom you know.

I will re-open the tag set tomorrow to allow additional nominations of 2 fandoms per person - please limit this to things you want to request. The tag set will close again within 48 hours of sign-ups closing.


App!
As sign-ups progress, karanguni's app may make it easier to find requests by fandom. This is updated on request and will say when it was last updated.


Sign-ups will end at 11:59pm EDT on 21 August.
