The site has been designed to work best with Internet Explorer 4 or later, or Netscape Navigator Version 4. Although older browsers will work, elements of text layout will be lost and may not appear as intended. 

Portions of this site may require a javascript enabled browser.

However, users sometimes report that they are still seeing very old or out-of-date pages. 

This is usually because their web browsers are displaying cached sections of the website - pages stored on their computer by the web browser - rather than the most up-to-date content retrieved from the World Wide Web.

To ensure you are viewing the most recent version of any page:

Make sure you are connected to the Internet.

Press Ctrl and REFRESH (for Internet Explorer) or Shift and RELOAD (for Netscape/Mozilla browsers). 

This will force your browser to retrieve the entire web page from the remote server.
