Administrators have full permissions on the system. They can create/edit content, publish content and manage users. They can also unlock or publish content that is checked out to another user.
Each tome has a single admin owner - the user who created it.
Admin owners have the same permissions as administrators.
The features and options available within a tome will derive from the package which the admin owner of the tome has with tomehost. For example, if the admin owner has an enterprise package, any tomes they own will have enterprise features available.
