In a moment of "Holy crap, this is a lot of work," I sat down today and built the Template system for TRHBlogs. That's right, now you can make your blog look at least a little more different than everyone elses.
There are currently three templates: TRHBlogs Basic (this is the design that you've all been stuck with), Paper Files (a little more traditional blog look) and Binary Simplified (based on the BlogRemote look, with less stuff loading).
Right now, the only skinable page is the current entries page - but as eventually the entire blog will be skinnable.
Update: The templates now apply to the entirety of the blog, entries and all.
Update: A Fourth Template, Industrial, has been added as well.
