Check out, part of the community forums at . You have to be a registered member to view or post. At the moment I am getting the error message that the login/registration page is “temporarily unavailable.” I was unable to sign in to check it out but by the time you get this, hopefully you will be able to get in.
EDITED TO ADD: I can now get in and it is a really good place. Read the instructions before you post. Those instructions in themselves are good writers’ advice.
EDIT 2 for Word Press: Since writing that post I found out about Scribophile.com.
