I just received an email making the "extra 3 months for subscriber id" offer. I assume the email was sent to the old subscribers; therefore, they already know I was one (50+ years). How would I know my subscriber id? I know it was on the mailing label on the paper, but I did not save any papers. I responded to the email that they are not making any friends with this policy.

EDIT: I just received a reply from "Joe Tripp". He says if I enter "SUBSCRIBER" in the ID field, they "will attempt to validate your subscription". The problem, of course, is that, if they don't, I've only received 12 months.
