Rated 3 out of 5 stars
I recently installed this add-on. When I clicked on the icon to activate it, it went to , and the page had the message, "The service is no longer accepting new registrations." Unfortunately, I can't rate this add-on for usability, but I must let people know it apparently won't work unless you are already registered. I'll give it three stars for a medium rating to not skew the ratings.
