Wikipedia's Definition of a web-based CMS:
A web-content-management system (WCM, WCMS or Web CMS) is content management system
(CMS) software, implemented as a Web application, for creating and managing HTML
content. It is used to manage and control a large, dynamic collection of Web material
(HTML documents and their associated images). A WCMS facilitates content creation,
content control, editing, and essential Web maintenance functions.
Bottom Line: Your new CMS is a powerful platform that will allow you you to have
full control to maintain your content.
A user account consists of a user name, email address and a password. User accounts
are assigned roles that determin what pages they can view and when functions they
can perform once they have logged in to the web site. User accounts can be assigned
multiple roles.
User Accounts and Roles can be managed by the "Role Administration" role.
