FYI there's going to be an XF Big Bang held this year. This is a major collaborative effort between writers and artists. Writers are to write a minimum of 20k words, and the artists will create artwork or vids for the stories they're assigned to. The stories/art can be gen, het or slash.
Here's the FAQ:
Support and squee group: omg_xf_bigbang
So far I haven't seen any slashers sign up for either groups. *sadface* I'd love to sign up in the artist category, but I'd love it even more if I had company. :D
Anyway, feel free to pimp the xf_bigbang far and wide. :)
