When creating a multi user subscription, the creator of the subscription becomes the Administrator of the organization's subscription.
Once the account has been created, the Administrator can add and remove members from the group.
Click on the Organization tab on the left menu.
Enter the email address of users who should be added to this subscription. Note: The user must already have registered as a user. The user should click the Register link and complete the registration process. Once this is done, the Administrator can add them to the subscription by entering their email address and click Add User.
The user will receive an email confirming their addition. Either the Administrator or the User may remove them from the subscription at any time.
