There are eClass courses that are taught by more than one instructors, or that have teaching assistants (TAs) assigned. No need to create a separate iClicker course for each of your colleagues.
Create one course and invite your colleagues as a co-instructor or as a teaching assistant (TA). The permissions are similar to eClass roles.
Follow the instructional link How to Share your iClicker course with your colleagues and view the course permissions based on your colleagues' role in your eClass course.
