Posting to the AO3 Collection
Done with your secret santa prompt and ready to post it? Here’s what you gotta do. First get your work all ready to go on AO3 (filling in all required information like rating, fandoms, title, summary, etc.), then before you post, go to the Associations section.
Start typing supersanta2025 in the “Post to Collections/Challenges” field and select it from the dropdown. Then in the “Gift this work to” field, type your prompter’s AO3 name and select it from the dropdown.
Once both these fields are properly filled out, go ahead and post your work. It will stay hidden until the Supergirl Christmas 2025 collection is revealed on December 25th :) Please make sure to add your work to the collection by the deadline of December 20th.
You can view and edit your work before the collection is revealed here. It will be the only one visible to you, so just scroll through till you find it! (Note: As the collection is moderated, it might not appear immediately. This does not mean you uploaded incorrectly! It will be up shortly, and in the meantime you can also get to your work via your statistics page by the works listed there.)
Starting a few years ago it’s also been noticed that the collection will not populate when you type it into the collection field! That doesn’t mean it isn’t posting there, it’s just some weirdness on AO3’s part. As long as you have the correct collection name in the field, it will post as unrevealed.
If you’re anxious about whether you have it typed correctly, there is a “Post to Collection” button on the profile page that will auto-populate it for you and show the collection name as selected.
