Well, I've lost my advertising here. Looks like Google is insistent that I validate my address by entering a PIN that they supposedly sent me. I've requested that it be re-sent twice, and still have not received one. They won't send me another. So I'm trying to deal with their customer service people, who apparently don't exist in any real form. My address is correct, I check the box a couple of times a week, and still nothing has arrived. They provide no other way for validating your existense.
