Well, alright! MT 2.2 is finally out and now it supports MySQL for storing everything. The upgrade was painless. That means I have complete control over dynamic access to my blog data. I can access the tables right from PHP, so there's not much that can't be done. Thanks again Ben & Mena! Oh and double thanks for putting the MySQL support in the free version too.
Update: Hey-- this new TrackBack feature has some real possibilities... if you're a MT 2.2 user, try it out on this entry!
