I think what Byz said, made a lot of sense. I do wish though, there wasn't that option when a person is making a group - to choose the 'invitation only' option. That way a member who's sensitive wouldn't feel hurt. If I was making a group, I would leave it open to anyone who wants to join. I can relate to the feeling - it's like you hear about a party that you never really wanted to go to - but then you don't get invited and then you at least wish you were given the choice lol.
