Have designated places where you can turn PK on or off...
With PK on you can hurt other players and the other players with PK on can hurt you
With PK off you can't hurt anyone and no one can hurt you.
You would start of with PK off because im sure little noobies don't like getting killed... And perhaps a little indicator above each players head if they have PK on (if you hold a button it shows up, kinda like spar rating) It would also help prevent NPC server crashing because of that stupid shout system, this way less people would DIE!
