I click on "notitle" and it takes me back to the main site and I can't see the reply =(

That means someone is referencing you in a comment, like in the tutorial comments section. It's happened to me a few times as well. For me it wasn't a big deal because I had only commented on one or two tutorials so I just browsed over to that thread to see what the comment was about.
