Works, now ! Rated 5 out of 5 stars

As the developer's response to my last comment stated, failure may have been due to several factors. With the same url as previously tested, the link was successfully shortened. Other servers do as well, an advantage here is that the resolution page displays WOT stats for the unshortened url, and this is a very good point I believe. It takes slightly longer to resolve the link because of call to WOT, I guess.
