What are the rules regarding the use of the maps already on this website? Would anyone be horribly offended if I were to loot the place for settings in my D&D campaign(s)? We're just the typical bunch of basement dwellers; not for profit and entirely unknown to anyone not actually playing.

I realize there is a map request system, but it'd be faster (and more fun for me) to just design a campaign around one of the many existing beautiful worlds and cities that're already here.
