What Site Can I Find It

You should use [COLOR=blue]this[/COLOR] one instead. A better version Well, when you are in a game online you press "pg up" and devmode activates. Note that it only works properly when you are host but you can sort of use it when you are not host. You press the ` key to bring up the console and type the devmode commands in that.
ok sunray it works
