Sorry if this was already posted earlier in this thread (haven't read the entire thing), but when I registered for the 4th Quarter promo (which I did a few days before October 15 deadline), it promised an e-mail confirmation, but I never got one.
I did have the foresight to print the confirmation page on the Web, but due to the website's cr*ppy new design, it is barely readable. (The words overlay a picture of some Starwood resort.)
(And yes, my e-mail address is current. Hasn't changed in years. Just made a couple of hotel reservations in the last hour, and got quick e-mail confirmation for those.)
