You will be the team's Owner. You are the only person who can adjust billing information on the team.
In addition to billing, you will have Manager tools. These let you invite other people to the team, update their accounts, deactivate accounts that are no longer in use, and set the role that other team members should have.
You will also have Instructor tools, including the Instructor's Guides for classroom use, and the ability to review Quiz Scores and the learning activity of everyone on the team.
