I just tried to use the MT-Protect plugin to password protect a blog of indeterminate name and location. It takes the cake for being in the top 10% of unusable software. In fact, Movable Type in general ranks high on that list; installing software extensions for it requires you to manually unpack the plugins while logged into the server, and then insert obfuscating tags into all your code templates. To password-protect the blog, I actually had to tell it “Enable Protection” in 3 places, and then I would have had edit all of the file templates (half a dozen more of those), and even then I wouldn’t use the Movable Type author database, you had to use some other website.
Movable type has its own development problems to boot. Useful plugins such as Cross-Blog posting require their own plugins to depend on (and they’re outdated, but that’s another problem). In all, it sounds to me like MT is going down, not up for all its convolution.
