There are 3 types of roles in the hub management page. These rights do not affect the user rights on a project. Its purpose is to determine whether a user can invite people to the hub, create new projects and manage the billing section. The 3 roles are the following:
Admin - A hub admin can manage users, create projects and manage the billing information.
Owner - Same as admin but also has access to the 'Delete Hub' function.
Guest - A guest cannot access the 'Hub Management' and 'Billing' pages.
