Heres a forum to help other Borderlands users find people to play Co-Op with if youre like me, and none of your friends bought the game.  (So what if it's a new IP, it's friggin awesome!)  So just put your PSN name down and maybe things some other people should know.  (Mic, class, lvl?)

 

PSN: Bulbasore

Mic:  Yes

Class: Soldier (Roland)
