When I saw I had to registered mail the guy I decided to Google search around and found out from someone griping on QRZ that he was likely to do something like that. I took that into consideration.
I wanted him to send it to ME so I could be the guy that forwarded the card so I knew I would get mine. I figured it was possible that some other ham might figure 'Screw the other guys. I got mine'.
I sent an over sized SAE and an extra buck and sure enough, that's what happened.
Incidentally some of you might remember that when I made the QSO I tried to get the Marines at the embassy to forward this for me. In the package I sent the Marines I told them if this was something illegal or against the rules to simply throw the entire package out and forget about it. I never heard from them which I kind of expected.
Further investigation tells me the embassies can't even drop a letter in the local mail for you.
