Where can I find a good online writing group for flash fiction?

Question

Flash fiction refers to short fiction, usually under 1,500 words per story.

Answer 1

I can't write anything under 5000 words, but a colleague of mine belongs to the Gather group and recommends the forums at WriteWords (which I'm afraid is currently full).

Answer 2

Have you tried putting 'flash fiction' or 'writing groups' into one of the search engines? Google, Yahoo or wikipedia? That might be your easiest route. As to how good any group might be, that's hard to evaluate until you get in and see how they respond to each other.
Good luck!
