We had twenty-nine fandoms represented as well as a cross-over and quite a few prompts that are not fandom/pairing specific.
I'm not going to list all twenty-nine fandoms (for which I'm sure you are glad *g*) but here are a few:
NCIS (a variety of pairings)
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 August and continues for the entire month of August.
If you'd like to pimp this on your LJ or any comm you think may be interested, please do so.
