Call my friend Laurie, who is an amazing writer, and leads writing groups. Wild writing she does is amazing.

I can't say I know of an existing group, but would be interested to know if you run across anything. I checked out the link in your other reply, and I don't think it'll work for me--I've been involved in groups that use similar methods, and it's not my preferred style of group work.

what kind of writing you doing? I'd like to work on my stalled novel, or possibly abandon it and start something new. I'm looking for a fairly advanced group of writers, not something for beginning fiction writers--don't mean that to be as snotty as it sounds.

good luck!
