Thank you for the replies, Flying Lawyer and jneugeba. I looked at the form again and think you're right.
Today's plan is to figure out the best/most cost effective way to mail it. As I'm only talking about USD 80 at the end of the day, I'm going to look to keep the costs down while trying to at least get a delivery signature. Too bad a trip to Germany is not in the works.
I appreciate your responses, and wish everyone celebrating Thanksgiving tomorrow a good one!
