We had twenty fandoms represented as well as quite a few prompts that were not fandom/pairing specific.
I'm not going to list all twenty fandoms, but some of the most popular were:
Harry Potter (a variety of pairings)
NCIS (a variety of pairings)
Starsky & Hutch
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 a lot of prompts in this section.
And remember, this is open to both writers and artists. Posting begins today and continues for the entire month of October.
If you'd like to pimp this on your LJ or any comm you think may be interested, please do so.
