I’m upgrading to WordPress 1.5 and doing some minor tweaks to the site menu and design today, so things may look a little strange for a while. It should be back to normal soon.
Update 4:39 p.m. EST: Well, there was a brief moment when I thought I’d lost everything, but order was soon restored. As you can see, the changes from a user perspective are quite minor. Let me know in the comments if there’s something that doesn’t quite work the way it should.
