Additional Notes
  1. The fly-out menu navigation of this site is designed to be accessible and cross-browser compatible. In Internet Explorer for Windows and Firefox, the links can be used with only the keyboard. The menu itself is made up of an ordered list that is usable with or without CSS or JavaScript.
  2. JavaScript, Flash, and CSS are not required to use this site.
  3. All text on this site, including the menus, can be scaled up or down by the user. Most current browsers allow users to scale the text up or down using the scroll wheel of their mouse in conjunction with the Control key.
  4. This site uses print CSS to make it more page-friendly when printed. Navigation elements are removed, but the breadcrumb and footer are left in place for context. Colors are reduced to black and white. For more advanced browsers, the addresses of links are printed immediately following the link text, and many abbreviations and acronyms are extended in parentheses on the printed page as well.
