One problem with this plugin. It does the same thing as the Permalink Redirect plug-in, but that prevents Google Analytics from tracking paid traffic The test for whether or not a site will allow GA to track paid (PPC) traffic is if you append ?gclid=Test123 at the end of a URL and hit return. If the argument stays, then something called 'destination URL' is in places. This should be fixed.
