This is just as much fun as adding an instructor. First, you have to make them a student. To do that, click on "List/Modify Users" in the "User Management" pane of the Control Panel and search for the instructor. Click on the "Properties" button next to their name. At the bottom, you can select their role in the course; change it to "Student" and click "Submit." Now that they're a student, you can drop them from the course as normal.
