Our policy

Many internet users with disabilities find websites difficult or even impossible to use simply because of the way they are designed. This site has been designed to provide information that is helpful and informative to pur visitors.

This website has been designed to be as accessible as possible and to be compatible with the types of adaptive technology used by people with disabilities, including screen readers.

As such, visitors can control the size of the text, the colours, the stylesheets and even use 'access keys' on the keyboard rather than the mouse to navigate through the pages.

Navigating this website

To navigate through this website, please use the menu at the top of the page. If you are using a screen reader, you can use the access key alt - M (press enter); this will take you to the main menu, from where you can use the tab key to navigate through the links.

Font sizes

You may change the font size of this document through your browser. In Internet Explorer, select View, then Text Size, and then your preferred size. In Netscape select View, then Text Zoom, and then your preferred percentage size.
