more on upgrading

I have fixed that issue by refreshing my templates with those provided by default in MT4. The only problem I can still see is that my per category pages are broken. This is not a surprise as I did some funky stuff in MT3 to make these work, and I need to understand both the new template structure of MT4 and possibly also test out some URL rewrite rules to ensure things work the same as before. I'm slightly worried about deadlinks, but it's not like this site gets a lot of traffic.
