Ah-huh
Looks like I shall be writing my first Wordpress plugin shortly, because it would be REALLY REALLY HANDY to have the ConDFW posts and pages change to the current date every time they're updated, as history has shown that we can't actually expect any of our users, including me, to remember to change the date on posts and pages when they're updated, so the tag at the bottom of each page merrily explains that they were last updated in 2008. The only plugin I can find (wading through the morass of Wordpress-update-related plugins that show up when you use "update" as a search term) only updates pages, was released in 2005, and doesn't work, in any case.
