I would like to know what happens with rights to peoples designs when "design your own plate is used".

I understand that images that are copyrighted such as other games cannot be used and uploaded to the gallery on http://www.faceplateaddict.com/ unless its for PERSONAL USE ONLY.

However, if I was to spark some kind of imaginitive design in photoshop and upload it to the gallery, do I get a percentage of that faceplate's sale and if so how much?

Also if I suspect someone has used my work and claimed it as their own and maybe edited the colour etc how does your site protect me??
