Well, the person who owns the hamachi group would have to set up most of it: password and administrators and everything. All I can do is delete my networks so you can recreate them.
So you would get Ra.Yellow, Yusei would get Obelisk.Blue, and 2492 would get Slifer.Red.
Then each of you could make a nice little welcome messege and send announcements to your dorm whenever.
So if you want to do this, just tell me and i'll delete my groups.
But if not, then that's fine too.
