Dan,

Search the archives for ideas on how to protect yourself when you run a round robin. There was one that had the participants take photos of the chips....like when the package arrived you had to take photos to send to the originator. Then you took a photo of what you took out, and a photo of what you put in. Those photos went to the originator, also, and he then forwarded the photos to the next recipient...who was expected to report if any of the chips that arrived weren't in the same condition as the ones in the photos. Something like that...

Have fun with it!
