I have Feedwordpress to import posts, and auto tagging for those imported posts. Now,I need to prevent the creation of similar tags to those I already have, for example, a new tag called "book" when I already have a tag "books" to which I want such a post to be assigned.
I installed Simple Tags which seems to be able to go through existing posts and merge tags, but short of doing this task regularly for every *almost* duplicate tag, I can't figure a solution.
I know that Drupal has a core feature for tag aliasing. Surely there is a WP plugin to get this? I've searched extensively, but can't find one.
