If you have sent someone and invite and they are not going to use the license, you can get the license back using the following instructions:
1. To cancel an invitation, go to the Admin tab, scroll down to the Students roster area. You can use the Filter Students option to filter by Pending students.
2. You can choose to either select all students by checking the box in the upper left corner of the Students section or individually select students by checking the box next to their name. After making your selections, click on the red Cancel Invite button. This action will return the licenses to your Available Seats category located at the top of the Admin tab.
