The flash demo is designed to be comprehensive enough to replace the live demo usually required for a pre-sales customer to evaluate the service. By default, a viewer will see the overview of the service.
However, the flash demo does have a MENU bar on the top left side of the browser screen (The vertical bar with the title "MENU"). By clicking on the menu bar, a slide-out menu item list will display and provide you with sections of the flash demo that you can pick and chose.
The slide-out menu also provides links to other pages that might interest the viewer; this includes pages for pricing info, requesting a live-demo, the company website, etc.
