posting info

_{*if you have any trouble seeing the images, please right click on them (control/command will also work) to view them in another tab/window.}

—FOR ALL CREATORS you can view your assignments on the sidebar of your ao3 homepage & you will want to update the publishing date to the date the exchange goes live IF you upload prior to the exchange's go-live date.

—when you fully upload & publish your gift, please make sure it is gifted to your assignee. clicking the assignment box will add it to the exchange and gift it to your recipient for you.

—ARTISTS when posting your art on ao3, you do have to include some text, but not much! feel free to caption your work accordingly. for a step-by-step walkthrough for how to upload pictures to ao3, please see below!


💫 1ST: you will want to make sure the posting box is in "rich text" mode to make things a little simpler. click the picture icon in the toolbar.

💫 2ND: you will input a link to your image. hosting your image on a "permanent" hosting site (ex: flickr) is advised so that your links don't break.it is important to note that on ao3, all images need their own unique, individual URL to show correctly! some sites may only give you a post URL if every photo is uploaded individually.

💫 3RD (OPTIONAL): if you want to center your images, it's easiest to add a little text next to your uploaded image, center align it, then delete the text.

info for pinch hitters

💫 sometimes, life happens and people who signed up can no longer complete their gift. if you are open to taking on multiple requests, or if you ONLY want to sign-up as a pinch hitter, you are welcome to do so!*NOTE: you are NOT required to take a pinch hit if you sign-up as a pinch hitter. you will only be contacted to pinch hit if someone else drops. at that time, you can confirm if you are willing to complete the requested pinch fill or not.💫 you are able to "register" as a pinch hitter on discord in the #role-assignment channel.

frequently asked questions (FAQ)

— Q: if i want to request/offer multiple tags, how do i do that?A: there is a request section and an offer section.✮ for example, if you are requesting a modern AU or a royalty AU, you can indicate modern setting in the additional tags section & you can indicate the royalty AU in the optional tags section.✮ similarly, if you are offering to do either a royalty AU or a modern AU, you can indicate these tags in the additional / optional boxes, depending on availability within the tagset.✮ for clarity: the optional tag section is there to address any tags that may not be covered in the broadly required "additional tags." match ups will work against any tag (additional or optional) for matching purposes.


— Q: can i submit multiple requests/offers?A: no. each participant is limited to one (1) request and one (1) offer. however, you are welcome and encouraged to include multiple prompts within your request.


— Q: does my offer section need to be as long & detailed as my request section?A: no. the offer section can be really brief and it is optional. it exists primarily to confirm that a giftee's DNWs don't clash with a potential gifter's.for example:giftee: DNW fluff
gifter: i’m only interested in writing fluffso the host/moderator would aim to make a better match.


— Q: how do i pick the request(s) & i prompt(s) i want to fill?A: each registered participant will receive an assignment in ao3 for their required fill. participants are matched against indicated tags, ratings, etc.as for selecting a prompt, you are welcome to pick any prompt from your giftee's list to fill. gifters are expected to adhere to giftee like & do not want lists.


— Q: can i write fills for multiple people, not just my assigned giftee?A: yes! treats are welcome and encouraged. requests will be visible under the "requests summary" tab on ao3. you can gift an additional fic to any user in the exchange + add it to the exchange collection as long as submissions are open.


— Q: what do i do if i have questions about my giftee's prompt(s)? how do i ask for clarification?A: since the exchange is anonymous (meaning: gifters remain unrevealed for 1 week after gifts go live), you will want to reach out to the moderator, ash @quillifer on discord to facilitate. ash will act as an intermediary between gifters and giftees to retain the element of surprise for the exchange.


— Q: do writers only exchange with writers, and artists only exchange with artists?A: no - assignments are done via lottery system. ao3 matches against selected tags in common, meaning that artists may be assigned to writers or other artists, etc. the moderator(s) will review the match ups to ensure that gifter and giftee DNWs are not misaligned before assignments are confirmed.


— Q: are personal designs/headcanons for sonic & shadow allowed in fills?A: as long as your giftee/recipient does not have any DNWs that clash with your designs, this is absolutely allowed & encouraged!


— Q: are both traditional and digital accepted?A: both formats are absolutely welcome and accepted. for traditional work, if you can scan it and/or take a well-lit picture, that would be ideal.


— Q: are humanized versions of the characters (AKA gijinkas) allowed for this event?A: sure, as long as your giftee is okay with them! i have now updated the default tagset to include “human/gijinka designs welcome” to make it easier to match with folks who are open to it.


— Q: what sort of creations are allowed? (fic, art, etc.)A: pretty much anything creative is cool as long as you, a human behind it, are 100% responsible for it and did not steal anything from another creative (this includes using art/assets without the originator’s permission.) work(s) must be new to the event and must meet your giftee’s criteria.historically speaking, fanfiction and 2D fanart are overwhelmingly popular for this kind of event. as long as you have an ao3 account and you do not use assistive/AI materials in your work, you’re welcome! podfics, meta, animatics, music, & more are all accepted and encouraged.


— Q: is it possible to exclusively match with creators who are in the same age-range? (e.g. 20+)A: unfortunately, given the high volume of people interested in participating, i cannot guarantee that you will be matched with someone in your age-bracket. however, sticking to M/E content for your request & offer will more likely match you to someone in that range.if you have concerns about creating a suitable piece for your giftee, please DM me @quillifer on discord.


— Q: where will the final works be posted / shared / etc?A2: the final works for the 2025 exchange will be posted in the AO3 collection @sonadowexch2025.there will be a 1-week “blinded/anonymous” segment where creators will not be able to advertise their works on social media. after this 1-week period, however, participants are encouraged to tag the event accounts for promo post shares.→the event itself has bluesky, tumblr, and twitter/x accounts.


— Q: how are extensions for this event handled? what is the policy around them?A5: the general rule of thumb is, “communication is key.” if anything is going on in your life, let me know! there will be pinch hitters available to fill in the gaps for people who have to drop out and as moderator, i will be working to make sure everyone has a gift within the reveal period of jun 20-22.if you’re running behind & your giftee only has 1 gift queued up, i will let them know the expected date of receipt and continue to work on making sure they get a gift.
