I’ve finally upgraded to the latest version of MovableType. I was sore tempted to swap out to WordPress, since in general I prefer using open source software and I’m not all that pleased with MT’s Passport-like play for lock-in, but in the end convinience and the prospect of having to redirect hundreds of blog entries and comments won out.
The biggest upshot of this is that comments are now working again (I’d disabled/broken them in a diluge of spam a while back), and hopefully the latest version of MT Blacklist is up to the task.
