I used to belong to EditRed (formerly Spoiled Ink) before it closed down.  It was a site where you could post your writing for critique and feedback and it had a discussion forum too. 

Any other suggestions on good (free) sites for writers?

Anybody?

For editing and critiques, nothing worth talking about really. I know a site that encourages people to write but not alot of editing goes on their.

You might want to try the Nanowrimo.org they have a forum that lists sites that their members use.

This is a great writing forum I belong to. 

CR

PS- Forgot to add they have an entire section for posting work and receiving critiques called the Writers Workshop.

This is a good site my daughter found, for younger writers, but it's a good place to have your writing critiqued and to help other writers with their work:

BTW, I've found a really good one, but it isn't free.  Fairly low cost though.   Fanstory.com

I also like opensalon.com.
