It certainly won’t be closing, and submissions will most likely stay open.
Currently, we have, in addition to Doctor Who and Sherlock, fic from the Buffyverse, Glee, Good Omens, Homestuck, Jeeves & Wooster, various Marvel comics, Shakespeare, and Star Trek.
This is not a rec site, and the moderator has no control over what people submit.
Yes! Just make sure that it’s clear that it is a sequel or prequel in your notes.
The point of the challenge is to create more works, so while we would prefer fanworks, original pieces are welcome as well as long as the story is self-contained.
Oh, absolutely! I’m going to go and clarify the rules page now, but you don’t have to be on the ace spectrum to contribute, and things like aromanticism, demisexuality, grey-asexuality, and queerplatonic relationships with ace/aro elements are absolutely welcome!
Oh, absolutely! You can write about any character you choose to, whether or not they are canonically or commonly perceived as asexual :)
The purpose of Asexy April is to generate new work — sorry :( — but if you wanted to start a rec blog for ace!fic, I’d definitely want a link!
