This site is best viewed using the Firefox browser for Windows, or Safari for the Mac.

This website is designed to be as accessible as possible to all users – including the partially sighted.

The size of the text in this site, including all text in menus, can be resized using the settings of your browser and can also be easily interpreted by screen-readers and other technologies.

Because of this, some browsers that do not fully support web-layout standards (particularly older versions of Internet Explorer) may have trouble displaying everything correctly.

If this is the case, it is strongly recommended that you upgrade your browser to Firefox. It is free, easy to install and has many security and other benefits over Internet Explorer.

We trust that you will support the reasons for taking this approach.
