Last night at the Atlanta Drupal User Group they added in a feature to their meeting that I have yet to see at other user groups.
At the very beginning they asked everyone to say their name, what they did, how they learned about the group and how long they had been working with Drupal.
As a newbie to the group I found that 3-4 minutes to be extraordinarily valuable in getting a feel for the room and the group as a whole.
I'm sure that format is prohibitive to larger groups, but less than 30 people should take less than 5 minutes.
What other meeting features and formats have you seen groups use that you liked or did not like?
