Serious suggestion:
When registering / logging in don't ask for name, just put nick which is currently used by player.

Bug:
When I tried to connect again after registering I could't login, it gave me "This user someone is using", even tho I was only one online.

P.S.
What's the purpose of /guns ? I think it's unnecessary. You kill - get money - buy gun, otherwise you don't. I suggest to remove it or make a cvar which would allow to disable it.
