Give and get support around quitting
Ok, so far it looks like this is kind of an IM setup. You just have to write your own replies. It doesn't look like you can respond to individual comments like on the Blogs page. So if you don't want the entire group to see what you write, that is if you are trying to only talk to one person, I think you have to click on their icon and send them a message, or leave them a message board comment. If there is something on your mind, you can start a group discussion, or just respond on the main page like an IM. That's it so far, I'll let everyone know if I find anything else out.
Thanks, James
