Woohoo, one more Aussie to fill the ranks, welcome mate
Enjoy your time here.
I dont think anyone is mapping just yet, as nothing has been released to map with, I guess you could start with Q3 Radiant or whatever it is that makes maps for Quake 3 and then convert them over to the format being used in MoH:AA, but we'll have to wait and see
Anyways again, welcome, and if you have any problems just give me a yell
