This is why I'm appealing to the cartography experts. All that sounds very impressive, but is near-incomprehensible to me. I'm hoping someone with the skill and tools you suggest can step in to help.

Fight On! is a fanzine dedicated to the old school roleplaying revival and is assembled quarterly by its editor. Issues are not free as you mention, but the net profit pays the editor beer money for his hard work to see each issue to completion. Contributors receive a PDF of the issue their work appears in, retains all rights to their creations, gets an opportunity to showcase their work to a growing audience, and gets the satisfaction of sharing their work with the gaming community at large. It is understood that this is not enough for some creative individuals, and if that is the case here, it's understood. I'm contributing the article that the map will hopefully accompany because I consider it an exciting project worth sharing and not for monetary gain.
