I'm currently migrating the site over to the new version of Drupal, 6.2. I've been quite behind with the releases, with the latest 5.x release being 5.7, I had 5.2 installed.
Note to self: when next migrating content over, don't accidentally delete the directory that has content file attachments.
Unfortunately the previous greeny theme that I liked hasn't been ported to 6.2 yet, so I'm using the default Bluemarine theme for now.
