Highlight changes that the professor makes so that they are easy to find
I was working with the CourseSites.com Blackboard webpage that we are using for the organizations until Community Spaces are available, and I saw a feature that is really nice for students and would solve the question--How do students know if something has been updated? The feature was a "What's New" box on the Dashboard of the course. I'll include pictures for you. If can be set to show an internal link to anything on the LS course that has been updated in the past few days (whatever you up there decide is the best time line to display).

Is there anyway we can tell if the instructor changed the syllabus and see past versions of the syllabus? I believe my instructor changed it and didn't tell us about it, but I didn't print out a copy of the previous version. How can I get access to that?
