I'd go as far as saying that 90% of the active members of the site are either roleplayers now, or were roleplayers at one time. A small percentage of the members are fantasy fiction authors, some are cartographic professionals, and some RPG publishers which fill up the remaining 10%.

I am roleplayer, sometimes GM, sometimes player using Pathfinder, sometimes D&D 3.5. I am also a professional fantasy cartographer, that is I create maps on commission for publishers, as well as being a co-publisher myself.
