This page is used to hold homework examples. Thus, the pages linked from here do not have the "commercial" display layout of the home page, with icons and menus. They tend to be vanilla pages just to illustrate a specific functionality.
To underscore this difference, these homework pages will have "You are here" guideposts instead of the Goto: left navigation links.
He who asks a question is a fool for five minutes; he who does not ask a question remains a fool forever -- Confucius
