in some cases, administrators may need to assist faculty or staff with manually enrolling or removing small numbers of users. Doing so manually through the course UI is quick and can be done in less time than it takes to correctly format a CSV and then upload it to the administrative area. Here's how to accomplish that.
Go to the Administration tab
Search for the Course
Using any of the available criteria, search for the course you wish to enroll or remove users from.
Click on "View"
Go to the "People" Tab
Click on "Add Students"
Search for the User
Click on the small "+" button under "Add"
Check off "Faculty" if enrolling an instructor
Click the "Save" Button
Once you've hit the "Save" button, any users you've searched for and added will be put into the course.
