A nice feature of the Website Manager system is that you can define an Author or Website Administrator by individual Website you've created. How this works is that you create a user profile, and assign it to the website he/she is responsible for. When the user logs in, they only see the website content which they've been assigned rights to.
Some application of this could include (but are not limited to)
- A Brand Manager who is responsible for content updates around a brand's website
- A Operational Manager who has responsibility over a Business Unit or Subdivision
- A Marketing Consultant who has been recruited to create inbound traffic for a particular landing page
