Well I can tell you that were very short on people here with good geology knowledge that can impart a bit to help make maps or software for making terrain / maps. I'm always looking for people with some knowledge of the physical properties that drive geological processes especially erosion and river formation. Many people here just want a map to play their next game or one for a book they are writing. Not many of the fantasy books had proper geology for their maps and that's especially true of the early ones. People are making more of an effort in recent times which may be due to their expectations and demands being set higher every year.
