There were quite a number of fandoms represented, from there really well known to the smaller ones, as well as a couple of cross-overs and some prompts that are not fandom/pairing specific.
But even if your fandom hasn't appeared and you'd like to write a story/produce artwork, check out the 'fandom/pairing-free' section - there are quite a lot of prompts there.
And remember, this is open to both writers and artists. Posting begins on 1st May and continues for the entire month of May.
If you'd like to pimp this on your LJ or any comm you think may be interested, please do so.
