hi there, no worries!!! the TOS in the desc. of the adopts is pretty much it! 

"*use the design (with direct credit given to me or weremars at least once)
*use the art (with credit every time)
*change the design as you please
*resell for what you bought them for (plus added cost of extra art if the artist gives permission)"

You don't need to let me know if you ever decide to trade/resell/etc.!! :-DDD
