Did you know...

In Blackboard 8.0, the Grade Center can hide students that are disabled, and won't show in your grade list.

When a student has dropped a class in Webtools (student is disabled, in the Blackboard course after 24 hours), you can then go to the Grade Center and HIDE those disable students.

Go to Manage and scroll down to Show/Hide Users. In the window that comes next, select the students you want to Hide, and click Hide Users, then Submit.
If you would need to show them again, click Manage, scroll down to Show/Hide Users, and in the window that appears, select the Hidden users and click Show User.

This will help your grade book from becoming cluttered or confusing.
