I need that each page is administered by one person or group of persons.
Do I need to create one role each for every page I have to administer(Page1 administrator, page 2 administrator) or can I just create one generic role named "Page Administrator" and have some thing like a user having Page Administrator role can manage only page1 and similarly another user having the same "Page Administrator" can only manage "page2"? This is to avoid creating as many roles as there are pages in the system.
