There's an function int the plugin API called GetPlayerKey(int). But to be honest I'm not sure what that is. I've just noticed it increases by 256 with every player that connects.
The key is just a unique identifier for a player who joins the server. maxorator knows much more about the specifics than I do, to me it doesn't seem to serve a purpose for scripters.
TBH I was thinking the same. What confused me was the fact that it increases by 256 with every player connection. So I wasn't really sure. I should probably ask maxorator but since I don't know him I'll probably leave it at that :D

Obviously :-\ But I doubt that's what it is for.
