The Dispatchers tab can be accessed by clicking 'Admin' on the Dispatch Hub's main user interface. It contains a list of users who have access to Dispatch Hub, along with their roles and permissions.
Roles can be added with specific permissions. For example, a role can be created with access to Field View, but no permission to access or edit any of the other tabs like Schedule View. This gives security that important changes are only being made by people qualified to make them.
