We’ve found two plugins that make editing a batch of posts and categories a snap! First, use Term Management Tools by Scribu to turn all those categories into a nice easy to manage hierarchy of main categories, sub-categories, and tags.
Then use Batch Cat by Lenin Lee to add /edit / remove the appropriate terms from the posts in bulk.
I just edited several hundred categories and 1,700 posts in about 30 minutes.
We heart plugin authors!
- go to Plugins -> Add new.
- Search for the title.
