Fortunately for those of use who use Movable Type, there are several folks who devote much of their free time to understanding, exploring, and extending the capabilities of MT, and are willing to share that knowledge with the rest of us.
Here's my roundup of good sites (in addition to LMT) to investigate while learning how to use Movable Type (I will add to this list over time):
- Movable Type Support Forums - The MT Forums should be your first stop for questions regarding Movable Type. Before posting, read this thread which will explain general rules of conduct and the best way to find answers. Generally, play nice, read the MT Manual (3.2) first, and try a search before posting to see if your question has already been anwered.
