Question: I've ugraded to 2.3, moved all of my UTW tags into the native tagging structure, and I'd like to clean up my mysql database. As far as I can tell, the tables that I should delete now are:
wp_post2tag wp_tag_synonyms wp_tags
Of course, it goes without saying that I'll do a backup before doing this...
For bonus points: what do I delete out of the Options table?
