I just set up a new and improved theme for the site using a free template and adapting it manually to work with my blog. BlogEngine.NET comes with several good themes, but none of them were exactly what I was looking for (and I also wanted an excuse to dig into the blog code a little more). It was a lot of fun to do, and, while looking through BlogEngine.NET's source, was very interesting to see how ASP.NET is supposed to be done :). There are probably still a few rough edges, so please excuse the mess.
