Lol that shouldn't even be in there. You can now make everyone with that script leave/quit.

Also. The use of that on text will screw up the rest of your script. You should use

on $*:TEXT:^!(exit|leave)$:#:{
$iif($regml(1) == exit,quit,part #) LastBattleScript, Requested
}

Ask jethro, i'm sure he will agree with me. He likes $regml(1) a lot aswell! :D
