Here you go.

sub EVENT_SAY
{
if($text=~/Hail/i){quest::say("Greetings, $name. If you wish to follow the ways of discord, simply tell me you wish to be what we call [pvpon]. To follow the ways of Order and remove your "PvP" tag, simply chant the words, [pvpoff].");}
if($text=~/pvpon/i){quest::say("Good Choice. Destory the shackles of order, $name!!!");quest::pvp("on");}
if($text=~/pvpoff/i){quest::say("While you will regret putting yourself back under Order, I cannot refuse your request.");quest::pvp("off");}
}

Also, this is in a sticky although I redid it to your exact requests, so, next time look around a little =)
