Your group is finally meeting! Are you excited? You should be excited.
First, your whole group should be commended for finding a time when everyone is available. Good job, people. The hardest part is done, but you still need to do a little more preparation for your meeting.
Because it's so complicated to get everyone together, it's super important that you work out the agenda for your meeting before you actually meet. You want to make sure that your group uses its time effectively and efficiently.
