If you are on our hosting, then it won't really work. (There might be a way, but I'm unsure right now how to do it. I will test)
IF you are only on our stats, unlink your stats from your wordpress blog by going to the services and stats tab and logging out of your blubrry.com account. Once that is done, you should be able to change the redirect URL's around in the services and stats page.
This will, of course, mean that you wont' get blubrry stats in your dashboard. I will check to see if we can make a change in the plugin to allow you to order the redirects.
