I belong to another Forum (not CAD-related) that has a nice feature. When looking at a list of Discussions, there is a small icon beside the Discussion title. Clicking on this icon will take the user to the Discussion, with the first un-read post at the top of the monitor (or screen). If there are no new posts since the user last visited the Discussion then the icon isn't there. I realize that this Forum has Discussion titles in bold print to indicate un-read posts, but being able to go directly to the first of those saves a lot of time and mouse-clicks.
