Hi Kris > I have noticed that since Google I believe it was, took over You Tube, they have not been allowing comments on any of the other videos on You Tube as well that I have seen so far.
So your question should properly be put to Google itself I would think rather than to Sive inorder to get the exact correct answer. I think Sive's answer is probably the correct one anyways & since I personally am just far too busy to chase after Google to get the right answer from them, I will leave it up to you to pursue Google if you wish to. So if you do & you get their answer back, please do inform us all here so we will know for sure as well. Hope this helps & that you understand my position on this. Cheerio.
