I finally made the plunge to Drupal 5.1 . As you can see, I'm using the default theme since my old theme doesn't work with 5.x. I will fix it at some point.

With this upgrade, I've turned on anonymous comments again. Drupal 5.1 finally added a "select all" feature when viewing comments, making it MUCH easier to delete spam. (Putting it on par with Wordpress which has had that feature for a long time.) Comments still have to be approved, just to keep boodebr.org from becoming a spam site when I'm out of town for a few days.

UPDATE: The theme is decent now. Finally got it working under IE6.
