If you visit the Create Content link you'll see multiple content types configured for your use. Each page, book page, story or forum is considered a basic content type known as a node. Thus, each of the various content types are particular types of nodes with specific functions and display characteristics:

• Static pages are a way for a content author to create regular web pages.
• Stories are posts which can appear on the default home page or another page. Static pages can be configured to display lists of stories.
• Each individual user on the site can have their own Blog page. An aggregate of all recent blog posts from all users is available through the Blogs link in the navigation header.
• Forums are much like any other threaded discussion forum where users can post to forum areas created by an administrator.
• Books are used for this guide, but can also be alternatively used for collborative projects (not covered within this documentation).
