The first night of a group meeting is often a good time to "get re-acquainted." This is an exercise our group often does to simply promote discussion. Everyone gets a chance to talk, and no one is allowed to go twice until everyone has participated. Each person simply chooses a category and then adds to the list in that category. Once a category is full, no one else can use that one (this helps encourage people to participate early rather than waiting until the end!):
