There is a feature in your Profile called "FORUM TRACKING" If you change it to "Yes: Highlight new posts for me", then when you click on the lists of Forums (left column of course pages) you will see a colored flag and check mark for the ones you have not yet seen. I have started using this and it is very effective. To change your Profile, click on your name (top right of home page) and click on the Edit Profile tab. The "FORUM TRACKING" pull-down menu is about 2/3 way down the list. Change it, and the scroll to the bottom of the page and click "Update profile".
