I am curious. Once I activate this plugin and tell it to "Re-Tag All Posts" .. if I don't like what it does or how it works, is there an easy way to just reverse back to the way my tags were and undo what was added by this plugin? Before I use it, I want to make sure that I can just reverse any tags that the plugin might create (for all my posts) if I'm not happy with the way it works. Is this possible? If so, how?
