Nick or nickname is where you put a cuple leters from you username, this is for finding randoms that may appear...
Example:

Players[0].Name :='Stupedspam';
Players[0].Pass :='********';
Players[0].Nick :='upe';
Players[0].Integer1 := 1; //1 - 4 fightmode.
Players[0].Active := True;

make sure you use 3-4 letters from your name other than the first cupple letters....and yes numbers work also.:D

Thanks;)
