Eric Kunnen and Santo Nucifora have created an incredible building block for Blackboard that gives you the tools you need to evaluate the use of your blackboard system, tools, and users.  I saw a sneak peak of it today at the BIE steering committee meeting.  Incredible.  You should check it out at their session on Wednesday morning 9:30 AM in Harbor 4/5.

I have seen lots of requests on the list serves for such a tool. They have built it, so check it out.
