The Amazons, B&Ns, do put the shipper's name address on stuff (and if you're shipping internationally by any method your name will have to be on things due to customs forms), but that doesn't necessarily mean you'll know who the person is unless you can somehow identify their handle with their name. Sometimes you can; sometimes you can't.
I sent my SS a thank-you note expressing my joy of all the Xmas movie dvds I received to the name/address on the shipping form, but I had no clue on who the person is because name didn't seem to resemble a handle. I even thought of looking at locations under people's handles on FT to try & figure it out, but when I saw in the first post the gazillion people who had actually signed up for FT SS & hasn't really posted on the thread I gave it up, and just decided to enjoy it w/o knowing. Same thing a couple of years ago.
Cheers.
