I used to offer the themes used on this blog as templates for Movable Type, WordPress and Pivot. Unfortunately, I no longer have time to maintain these templates, and I haven’t used them myself for several years.
You may be able to find the template files on sites such as the Web Archive, but please bear in mind that they were developed for old versions of MT and WP, and will almost certainly not work with the currently available versions.
Thanks to all of those who used my templates over the years, and I hope you have found them useful. If you’re looking for new WordPress themes, I would suggest going to the official WordPress theme directory.
