Himuro here. The forum I'd be glad to moderate is the GTAIV forum.
I've moderated a few forums before, most notable the now defunct Square Source. I've been coming to GTAgaming 4 years, although I recently joined last year. Up until now, I've tried to supply GTAgaming GTAIV boards with ample news reports and discussion. My attitude is pretty calm and relaxed, and I try to be helpful in any way I can. I'd be glad to help out gtagaming! Good luck on the process and thank you for the offer.
