So here's a fun party trick: Have you ever searched for something in Google while attempting to troubleshoot an issue, or just to do some light reading, you find the EXACT page you're looking for, and you get greeted with a nice friendly "You are not allowed to view this page, please sign up" notice? Try clicking the little arrow directly after the URL in Google. Click "Cached". Voila, free reading without the unnecessary hassle of signing up. This works best with most vBulletin forums, as it doesn't block the Google bot by default, as far as I know.
