Something similar, is
fic_rush_48 -- only on Live Journal -- where, once a month, a bunch of crazy folk get together and do 48 hours of cheerleading about writing, real life and whatever happens to be going on. There's an hourly check in post but checking in is totally optional. Do or do not, if you want. Cheer about your writing, whine about grocery shopping, toddle off for needed sleep... whatever you want. From 6 PM Friday to 6 PM Sunday (Eastern time), there's writing to be had.
It's warm and welcoming, the mods are laid back and will celebrate whether you write 100 words or 10,000 words.
If you're at all interested, you should follow
fic_rush on Live Journal. They post the basic schedule there and take opinions on which weekend that the Rush will happen. It's a low traffic comm, and it won't flood your flist.I got 2500 words done this weekend, more than I would have otherwise, so it was a success for me!
Check it out!
