Bantha's right - though my take is for 2 categories only.

Plus a visual indicator on the page like the small icons in the MP. Say red for all commerical use OK. Or Blue for non.commerical .

Obviously you need some form of checking to ensure the right box is, or has been ticked.

Oh, and this of course assumes that someone actually bothers to read the readme file (I have to be here - I hardly ever do).

Just as important is the wishes of the creator. Using the example of the cross prop which said not for nasty satanic thingys in freestuff. Thats more of a tricky issue, while I respect the belifs of the creator, they might not be mine, so whats the score there ?         

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