Quick Note: I just updated Movable Type from version 2.11 to 2.21. Upgrade only involved FTPing updated files to my server, replacing any existing files and folders that have the same name. No real big changes from previous version. Major addition was ability to use MySQL to store data (instead of Berkley DB) and "TrackBack, a peer-to-peer framework for communication between weblogs".

I'm anxiously awaiting the "post via email" feature that I hear is currently in the works.
