Okay, I'm totally in! As Wingshaw said, I'm not against investing some money and time in this book, as long as it doesn't cost a fortune. I'm also not against the non-profit idea. To me this would be more like a product made out of love for maps, rather than financial interest.

Deciding what (sort of) maps to include will be tough. I'd say we dedicate sections of the atlas to different kinds of map ( someting along the lines of Space & Scifi, World & Regional, Town & City, Structure & Technical etc.). However, that's stuff to discuss later, as we would first need to figure out how we're actually going to make this happen.
