I just read the PCT website, which I should have done first, and found this:
You will receive your warranty paperwork by mail soon after your notebook purchase. Please activate your Warrantech policy as soon as possible to avoid any problems in receiving service. If you fail to register before a problem arises, you may experience a delay in receiving service so that your paperwork can be processed. Using the info that is mailed to you, it may be registered at the Internet address – www.myrepairmaster.com
, by calling 1-877-263-7403 or by mailing to the address on enclosed registration card.
Which means that everyone should get some papers soon. Hopefully not a few months! But at least I know Warrentech should be sending something "soon".
