Tables are not used for general site layout.


The site has been designed so that the main body content is easy to read through its colour combinations. If you have any difficulty in reading parts of the site please contact us.


We have worked hard to ensure that our links are meaningful, and some links are explained in greater detail by using a title attribute.

We cannot guarantee full functionality of the website (in particluar the main navigation menu) if you are using a browser version earlier than Firefox 2.x, Internet Explorer 7 or Opera 9.
