I'm pretty new the YT upload thing, largely because of the prodding by other UU'ers here, "C'mon! Post some vids! Let's see whatcha got!!!" One day ALL my posts were gone and I had to re-upload them (there were only 6 or so, not a big deal). Then not long ago one of them lost its ratings and I had to re-enable the "allow ratings" or whatever it's called. I also notice that many of the comments are not sent to my email, like most of them are. Not that I get that many to begin with, my point being that all of these little things are either glitches in the system (it's a wonder YT works at all...), or something like a randomized hack causing mayhem to the delight of some pimple-faced punk with a computer in a basement somewhere. You get what you pay for I guess!
Why on Earth a "how-to" vid would be blocked in another country is beyond me. I can't even muster a funny reason, it's so weird. Maybe they were expecting the paint drying and instead got a uke restrung? See? Not funny....
