We believe the internet is such a valuable resource that it should be available to and accessible by everyone; to help achieve this aim, this site has been constructed to conform to best-practices for accessibility.

The navigation system can be operated with a mouse, trackball or keyboard. If you use a screen reader or for other reasons have disabled JavaScript, please visit our sitemap, from where you can access every page on our website.

Text size is relative to your browser's default, therefore you can increase or decrease it according to your preference.

Every image on our site has alternate text, except background images and inline images whose purpose is purely aesthetic. Likewise, Flash objects can be replaced with alternate content by disabling JavaScript. Please follow your browser's instructions on how to do this.

This site has been optimised for viewing at a resolution of 1024x768 pixels or greater. This was a design choice and does not affect our ability to create websites that are optimised for 600x480 pixels or 800x600 pixels.  

Whatever your browsing preference, we hope you enjoy your visit to our site.
