I've recently noticed that I longer receive any notification to when someone comments on my videos or reply's to one of my comments that I may have posted. I also noticed I didn't have that black column on the left hand sign which has your account options and also enabling me to make it that it only shows uploads. I no longer have that for some strange reason. I'm thinking that I may have done something in the settings and done something. Can someone please help me. Also it must hae something to do with my account because when I log out the black column's there.
