He used to be marketing guy of Nabi etc. He was leading the promo-team, which was a group of people hosting tournaments, making toribash related projects and such. Gman was also organising promotions for buying boosters etc. For example, you used to get a pack of cool items when buying a booster, the better booster the better items you were getting.
That'd be it.
@edit
Ah, and what happened to him. He err... is gone fishing. Kind of left tb.
