GSATC Professional Network Forums?

There are a lot of great groups around the upstate and we are trying to make sure everyone knows about them. We have previously tried php forums on our website, but we just got too much spam. We are now evaluating this tool as a replacement. It will allow us to allow the individual groups to have their own page which is connected to the GSATC home page and they can post meeting announcements with the ease of posting a single message to the boards. We are looking for lightweight and easy to use.
