I've heard the occasional aussie accent in voice, don't remember their names.
I know the squad I'm in "9 giap" has quite a few... dantoo, picko, mijoau, niknah0(me), f6bomber, phychoo, and maybe others I forgot.
I think the BBS needs more localized areas, I'm sure alot of players from japan, germany, etc. would like to get together and use something other than english.
