Pages
Pages are similar to Sections.
Pages can be nested; they can be used to put other applications in, like folders.
You can toggle between showing the content and the page with the link in the upper right corner. You can change the default view in the Administration of a page/section.
The content view can be one html page or it can display portlets of many types.
Because Pages can hold any HTML they are often used to display portlets from other web applications like Yahoo stocks, YouTube, and RSS readers.
Like all applications Pages can be moved around in the navigation with the( right click) cut and paste functionality( you can only past into another Page or Section).
