My younger sister has seen me playing BB and has checked it out and I've explained how it works and everything, and she seems really into it. She wants to join BB as well, but the problem is we only have this one computer so our accounts would register the same IP address. We promise to not scrimmage each other, to deal together on the trade market, or to share draft or other info that could be interpreted as cheating. We just both want to play without breaking any rules, so is there a way we can play on the same computer so that she can join?
