Thanks folks for all the replies. Seems my subscriptions are still there so far this time, and at least I can get mine, unlike poor shirenu!
I hate this crap where YouTube are now trying to make you use a different account name, too. Bunch of control freaks.
But where would we be without them.
I also love how the H!P channels have now gone to full HD in recent posts. There's no excuse for anything less, these days.
