You gotta be in your Server using a GM LV 99, and you gotta type:
@adjcmdlvl 0 @commands
doing all that will completely work.... and that command makes you choose what command should each GM Level have.....and the GM lvl of a player is 0, so that means that you gotta always put 0 when your on @adjcmdlvl when you wanna edit a players commands....
and by the way... DO NOT make a player use advanced commands like a player creating a gm, that would be:
@adjcmdlvl 0 @adjgmlvl
.....if you do that, your server would be ruined X__X, LoL XDDD
