I've mentioned online listservs where writers' hang out so I thought I'd be a little more specific for those unfamiliar with this.
Many writer groups can be found at listservs like Yahoogroups. Some are genre specific.
To find good groups, ask around. You can also search places like Yahoogroups for writer and genre specific groups.
My favorites for writers are
PNWriters (Paranormal romance and urban fantasy):
Worlds of Fantasy
In a later blog, I'll talk about groups which are excellent research resources.
If you have a favorite group for writers, let us know.
