I decided to re-migrate to WordPress.  Or is that un-migrate from the other blog engine?

In any case it was a painful migration.  My old blog engine can only export to BlogML format, but WordPress doesn’t have a BlogML import utility.  Someone created one a while ago but it only supports up to WordPress 2.5.

At present I’m missing a large number of posts from my old blog.  Until I find the time or ambition to import them manually, they’re just gone.  No big loss I suppose.
