Here are a couple of questions:
1. Can a person respond to a post in a group without joining that particular group? (There are SO MANY.)
2. I was told of the existence of this site by a friend (didn't hear the commercial). Is there a home page or somewhere here where an "Ex Plan" of some kind is presented? A concrete concept of what to do or not to do?
3. What are "friends" on this site. If someone invites you to be a friend and you accept - what does that mean exactly?
