Moshare have developed a very cool php-based category method that works w/ blogger blogs that are published to host servers via FTP. If you're on blogspot, this won't work for you, but if you have a server, bring on the heavily integrated categories. Another great method!!

i did find it to be the easiest and the more refined php method from the prior two i know of.
