There are an unusual amount of griefers in this game, not just scripters, but teamkillers/vehicle stealers etc.
If public multiplayer is to be viable, then a more understandable/userfriendly votekick system needs to be in.
Currently, having to type "#vote kick [userName]" is pretty obscure... and lets face it, people in general are pretty stupid so you can't rely on them to figure this out.
So if someone starts a #vote kick [userName]
Make it easy for others to agree or disagree via an onscreen prompt telling you to press some key, perhaps Insert or Delete.
Obviously, only one such vote should be allowed at a time, and each player can only initiate a vote once every minute or 30 seconds to avoid spamming/clogging.
