Heh. Anything done in November is probably ill-advised, with exams approaching and holidays and junk (especially in the US).
Anyway, I did start a community (
http://community.livejournal.com/art_prompt) to at least post some prompt ideas monthly for me and maybe one or two other people I know who'd be interested in doing it with me (I already suggested "art about the way tea tastes" a week or so ago, and it seemed to be a popular idea). Perhaps other people would be interested, and we could do regular monthly challenges, not just in November.
