Browser compatability

This site uses cascading style sheets (CSS) for visual layout and presentation. The site is best viewed in a 'standards compliant' web browser with proper stylesheet support, such as a recent version of Internet Explorer (6+), Netscape, Opera or Firefox.

If you are using a browser that does not support style sheets or an older browser with poor stylesheet support the content of each page should remain fully accessible although it will be presented in plain text format.
