Lazyweb request for help with mySQL (phpwiki problem)

Over at The Power of Many, the wiki-driven portion of the site is down because of an error of some sort in the “page” table in the mySQL database. I’m kind of stymied now and don’t know whether the error is even fixable, or if I’ll need to revert to a backup.
Please drop me a line if you are experienced with php / mySQL and think you might be able to lend me a hand. Thanks in advance!
Update: Nevermind. Andy Baio pointed me in the right direction. A data table had crashed. I was able to repair it in phpMyAdmin. All is once again right with the world. Thanks, everyone who helped,!
