[king sting]

I made a forum called talkin points.. and as a sub forum i made a forum called hello.. i made this guy mike mod of the talkin points forum, but it shows him as the mod for the hello forum also.. how can i take him off mod as hello and add someone new? he isn't listed in the admincp as a mod of the hello forum just its parent forum.. any ideas? lol do you follow me?
