How do I remove users from an Organization?
Click on a user's name in the Manager, and then scroll to the bottom of his information and click Remove from organization. You can choose to Remove or Delete his account. We recommend that you just remove a user. That way, his account is still accessible; it's just not part of your organization any more. It will become a Free account, and all of the restrictions of a Free account will apply. You can remove many users at once by selecting more than one of them in your Manager, and then selecting Remove. Make sure you click the Update button to save your changes.
