2. If you use ANY part of someone elses work, you should always ask the creator first.
   Not just because of copyright issues, but just common courtesy. Many creators will say yes.
   I always do.
    

3. If the maps are totally original. Then you don't have to tell the creator.
   But If you do you'll often find the creator will be really happy about it, and link exchange etc etc.
   Or maybe even offer to host your freebie.

Pinky - you left the lens cap of your mind on again.
