When a site doesn't redirect you to where you were after it nags you to log in to see content
God I hate this! Never fails, either. I’d be on a page of someone’s profile or some piece of content I’d like to see but I’m required to log in. Okay, I will do so. So I do and it doesn’t redirect me back! It just puts me in the front page, like no thanks, just bring me to where I was!
