About This Page Hack?

Does anyone know whether the hack used in the forumdisplay pages of this vBSEO Forum to show different "About this Page" descriptions depending on the forum and other information depending on the state of the user is a publicly available hack or if it's a custom job? I think it's really cool and have been searching everywhere for something similar but couldn't find anything close.

Check out vBSEO's Relevant Replacements option.

Thanks, the Relevant Replacements option will do the trick indeed. I've also just found a hack that might help with the user status part: Welcome headers - Improve community registration rates - vBulletin.org Forum

Hmm. I think I may have misread your original question.
