User blog:Cure Egret/Annoying Red Circle

Hello. I'm a new user here and I was wondering what the red circle with a number 1 in it means in the top right corner of the screen. It's been really bugging me and everytime I click on a new page, it appears each time. How do I make it go away and what is it? I'm new to wikias so I was wondering if you could tell me what it is.
