Beside the Topic if anything has been added to a Thread a Blue Circle or a Blue Star will be on the Left Side of the Title of the Topic. A Blue Circle Means it's a Topic that you have never Participated in and a Blue Star means that you have Participated in the Topic such as Commenting or Posting any Pictures or Videos to that Thread.
Clicking on a Blue Circle or a Blue Star will take you to the last page you last left off when you were in that Specific Thread. If there is no Blue Circle or Star means that there has been No Activity on that Thread since your last Visit.
Clicking on the Title of the Topic will only bring you to the very First Page of the Topic and will remove the Circle or Star Status for that thread so it's Very Important to click on the Circle or the Star to get to the spot you desire.
Hopefully this Information is helpful to you.
