Things should be back up and running, now under new and improved Movable Type 4.01. I labored to make the move as cosmetically transparent as possible and also make sure all the old permalinks still work. Please let me know if you see any weirdness or encounter any bugs. No bug or oddity too small to mention.
A few things had to be removed because they don't quite work with v.4, but I'll be seeking newer ways to achieve the same functionality, adding things in as we go. Thank you for your patience during the move.
