Im down with that postie. I also think we need a couple of "team leaders" these leaders would be guys that know stratagy and technique and would be responsible to teach the rest of us. One person I suggest is postie himself and maybe JZ? just a thought? 
I think there is also a good mutator out there for practicing off line, its called zombie. You have hundreds of zombies walking around that you can shoot. There is also a map for practising with the translocator, im not sure what that map is called, im sure someone that knows will post it in here.

Rock on guys!!!!!
