how did you do it?
this is from me playing in beta but it seemed to work fine as long as you setup the games EXE file to be OK with firewalls etc.
just go in GPGnet Host Custom Game, click the password box, tell everyone the password, enter password, click go, give in a min to boot up etc then done!
oh and anyone who played the beta, did you like the old loading screen better than this one?
