Creating a user in an organization:

To create a user in your organization, you must be an Administrator or owner of the organization. Then, you click on your organization page and click on the button called "Create user" in the "Membership" tab.

Here you must enter user information, and you can specify which device you want to add the user to. If the user is to be added to multiple devices, do this from the "Devices" tab afterwards. Here you can also remove the user from the device again.
