I belong to picowrimo on LJ (originally set up as an alternative to nanowrimo) though I haven't done much writing in the last year of personal upheaval. They're really supportive, but don't run all the time, just November originally, and now with June and July added. I'd join this new one but I like knowing most of the people at pico. Besides, it's only fanfic I write ATM. Maybe one day...
