After filling out dozens of pages of surveys (giving them my information as an IT professional) to get a few car magazines, I got this link in my email:
http://download.examforce.com/offers/sg_offer_pkg.zip

It contains PDFs of study guides for the following certification tests:
CCNA
Network+
Microsoft 70-640 Windows Server 2008 Active Directory
Microsoft 70-631 Sharepoint
...and one titled "Fast Facts: Managing and Maintaining a Microsoft Windows Server 2003 Environment" which doesn't appear to be for a certification.
Edit: Ok, that last one says it's a general guide for the 70-290 tests.

They aren't full of advertising, and seem pretty complete. The CCNA one sure looks like the CCNA studying I did some years ago.
