I just stumbles over the Cartographers’ Guild which might be of interest to map makers:

The Cartographers’ Guild is a forum created by and for map makers and aficionados, a place where every aspect of cartography can be admired, examined, learned, and discussed. Our membership consists of professional designers and artists, hobbyists, and amateurs—all are welcome to join and participate in the quest for cartographic skill and knowledge.

Although we specialize in maps of fictional realms, as commonly used in both novels and games (both tabletop and role-playing), many Guild members are also proficient in historical and contemporary maps. Likewise, we specialize in computer-assisted cartography (such as with GIMP, Adobe apps, Campaign Cartographer, Dundjinni, etc.), although many members here also have interest in maps drafted by hand.

The Cartographers' Guild is a friendly, open community, welcoming to everyone who pursues cartographic excellence. We love to share our maps, to help one another improve our maps, and to pool our mapping resources. Please enjoy your visit, and feel free to join our ranks!
