Enrolling Additional People Into Your Blackboard Course

Enter your course as the instructor and open the Control Panel. 

Under the Course Options Area, choose Settings.

In the Settings area, select Enrollment Options.

In the Enrollment Options area, select Self Enrollment, check today's date as the Start Date, and an End Date if desired.

Setting End Date to a date before today's date will disallow open enrollment.

Now, for the student to be able to enroll:

Have the new student click on the Courses tab near the top left side of your window.

Search for the course name in the Course Search box near the top left side of the Courses tab.

In this is example, onlinebb was used as a search criteria.  This resulted in the following results.  Since onlinebb is a course with this open enrollment option and the student is not already a member, the Enroll button appears (usually farther to the right than pictured below).  Click on Enroll, following the prompts to become enrolled in this Blackboard course.
