Went to the Drupal group last night, and they had a great idea as part of their meeting format. They had everyone in the room introduce themselves briefly. I'm not sure if we have ever done that, but it was awesome for a newbie to the group. I'm sure it only works for groups less than 30, but nonetheless it was a good idea. Figured I'd let you know since you visit so many groups, and this is kind of your "greeter" "newbie be welcomed" thing. Also, you may have other ideas you have seen at other groups to contribute to the conversation.
While you may think its funny that Jonese has joined, I will point out that he has not joined the CF group. Course, then again, neither have you. I'm going to have to work on some FAQs for how to use this site I see.
