Nowadays, you can find writers' communities all over the place. There are formal educational groups in M.F.A. programs. There are formal in-person and on-line writers organizations such as Rocky Mountain Fiction Writers (which I highly recommend, no matter where you live). There are informal, purely electronic groups (Betsy can probably address them better than I). Or, heck, get your writing friends together and start your own writers group using yahoogroups or whatever. Good luck and have fun!
Does anyone have a good writers group they want to brag about? :)
And don't forget to send us your speculative fiction stories. :)
