Yes, definitely planning on doing it again.

My current brilliant awful idea is to allow genfic as well as rarepairs, but I'm a bit worried as far as logistical nightmare. (not that there doens't mean there won't be lots of smut)

I think it varies by author. I know I mostly sign up for the writing, but that's just me and I'm pretty bad when it comes to keeping up with the fic I want to read. I think with others, it varies. Thoguh I can't imagine signing up without being interesting in producing the giftfic or art.
