well, that may be true for a TB you have in your hands.. but what about a TB that you (originally) dropped, and want to follow? After it's taken by some other cacher, it's no longer available in your inventory. As mentioned in another post, the Geeoh app would be able to do this, but I think it should be in the standard app. If I register a TB, I should have the option to keep it in my inventory! Or any other TB for that matter. Could this generate lots and lots of (move) notifications ... maybe yes, but that would be up to me right ..
