OK, I'm gonna admit I made the assumption that I only need to update the whole site at once. I guess it would be better to update the site in chunks. The only time a full update would be required is for things that have to be updated on all pages, such as adding new themes. There are also things I'd like to add to the site: an RSS feed for the blog, more themes, and a long-overdue update to the MUD page.
It would also be nice if I added a welcome screen separate from the current main page - I guess it didn't fit in the post. I'm also changing the default theme to Tiny Orange.
