Jean,

Check out NSAI (Nashville Songwriters Associataion International). There web addy is www.nashvillesongwriters.com.

Even though they are a Nashville-based organization, you do not have to be a country writer to enjoy the benefits of membership. All genres are welcome.

They have regional workshops that generally meet one a month--I'm sure there is one in St. Louis (go to the web site and click on the workshops link). The workshops are a GREAT place to get thoughtful critiques of your work. They also offer a professional critique service that is free to members. Workshops also offer nice networking opportunities in your area, and a good place to hook up with potential co-writers.

I'm sure you can attend a workshop prior to joining so you can see if it is to your liking. Give it a try.
