I recently made a change to this site to remove the 'www' from the front of the URL. Well, it turns out this caused a large number of headaches with WordPress (though I think the actual root cause of the problem lies in a custom .htaccess rule set that I wrote). Anyways, I'm going back to the old-school 'www' style URL until I have more time to fix it. If you see problems with the site, please let me know.
