A big thank you to everyone who contacted me!  The skin in question was identified and found, and I've made the necessary contact to handle the situation.

As Roslin stated in her post about this issue, I cannot stress enough how wonderfully appreciative skin makers are when nice people like you give us info on skin theft.  I know it's par for the course for this to happen in SL, but I still am grateful for your help.

Keep your eyes open and help your designer friends!

Thanks again!
