December 20, 2008It’s well past the time for a major rethink of my site. I’ve decided to use drupal which Jill and I have successfully been using over at jillandleigh.net, and version 6 looks to be quite a nice upgrade from version 5. Eventually most of the content will be converted over to the new site and…
