Hanz0's a higher-tier moderator or "admin" of Toribash community and Gman used to be a member of the nabi staff.

oh

But Gman left Toribash some months ago, so he's not longer a member of the staff.

Gman80 was considered the marketing guru. Now that he left, they say that it's gonna be a while before new item deals come out.

gman80 also developed a lot of the gaming side of things and headed the Promo Team.
For example, gman80 created Flames.

hanz0 is an Admin, one that patrols, in particular, the market board. He has always patrolled it and always will. He is also a highly skilled graphic artist and thus is perfectly suited to where he patrols. You could say it's his natural environment.
