a) speak up here, so I know to invite you/look for you/whatever
b) MAKE SURE I have your 360 live username!
c) Make sure you have Catan downloaded, your headset/microphone in working order, everything set up, etc etc., before go-time.
That is all. I think.
ETA: make that 8:30pm Eastern, unless people get mad about changing half an hour at this late date :p
