Ehm...impossible?
Look, the way GM's get <GM> 2 theyre names, is simple, they type ".gmon" or ".gm on", something like that.
then you can only type GM commands (such as .gm on) when the ACCOUNT you play on is an GM account -- how are your accounts GM's when gm's play on it?
it cant be =p

ALSO, the title doesnt really fit...gm in IF as horde -- you are the horde in there they are the alliance and ur in if, i mean like wtf m8 what is weird about an alliance in if xD
also in the picture you did /w <gm>vercy rite, you should just do /w vercy you prolly would've get him then, unless he putted unwhisperable, but that GM is just an add to see he's gm, but its not in his name.
