I have a rather unusual (I think) problem and I'm hoping that somewhere there's a plugin to help me correct it.
When I exported posts into WordPress about a year ago (from the dark ages - MT 2.661) all the post author names got discombobulated. I went into individual posts and manually corrected many of them, but that was too time-consuming and I still have about two years worth of posts attributed to all the wrong authors. I'm looking for a plugin that will let me batch edit authors, preferably from Manage > Posts though I'm not about to get picky. I've tried a variety of enhancing plugins but none of them have this specific feature, and searches have proved futile.
(Any kind of search and replace is not an option - the name 'patterns' change as our archive was so large I had to do the imports in batches, not to mention the year of posts made directly into WP.)
Any pointers would be much appreciated!
