Wow, these people really are getting worked up about one simple box that you can just close out of.  Your not forced to sign in, so if you don't want to, just don't.  You talk about how it is wasting your time, but you seem to have plenty of time to come on here an write super long paragraphs about this box that you could simply close.  Also, being rude, which most of these complaints seem to be, will get you no where really fast.  Good luck all.
