Templates are special pages that serve as a starting point when creating a new page.  Using a common template for related topics gives those pages a common structure.  To use one of the templates, simply select the template when creating a new page.  

Below is a list of the available templates. To add a new template, create a page whose title starts with "Templates/", as in Templates/Business.  When you create a new template, add it to this list so it's easier to find.
