I am trying to find out how many users can be registered to one Xbench license or whether this is limited to one user.
It would be great if you could clarify this for me.
Each authorized email in your Xbench Control Panel is entitled to run one instance at any given time.
You can add as many authorized emails to your Control Panel as you need.
The end of subscription is recalculated each time you add or remove a user to your Control Panel.
This 3-minute video shows how to set up a multi-user account in the Xbench Control Panel.
