I just realized that when I re-installed MovableType, all the link addresses changed when the entries renumbered themselves. That means every internal link pointing to my own entries no longer works, nor do any external links pointing in. Grrr... Oh well, I edited a few that I found, but there's no way to go back to the beginning. Not a big deal, probably, but one can get obsessive about these things - everything must be just-so dontcha-know.
