We recognise the importance of providing a website that is accessible to all users. As such we have made every effort to ensure that our site can be easily used by people with disabilities.

Accessibility features

We have introduced the following features to ensure the best use of our site by all of our users.

Access Keys

By pressing your browser's Access Key(s) and keys 1-9 you will access the top level pages in the order they appear in the left menu of the site. You can also access the home page by pressing the H key, Terms & Conditions by pressing the T key, Privacy Policy by pressing the P key, Ask a Question page by pressing the Q key, or this page by pressing the A key.

Headings and navigation menus

HTML heading tags are used to convey document structure. H1 tags are used for main titles, H2 tags for subtitles, etc. Navigation menus in this site are marked up as HTML lists to ensure that the number of links in the list is read out at the start and it can be skipped easily.


All images used in this site include descriptive alt tag attributes. Where an image has no use other than being decorative the alt tag is set to null to allow easy reading of the site by all users.

Font size

Most of the font sizes we use on our site are sizable. You can change the font size to make it either larger or smaller via your browser settings.

You can change the font size in the following ways depending on 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.


This site uses cascading style sheets for all visual layout. If your browser or browsing device does not support stylesheets, the use of structured semantic mark up ensures that the content of each page is still readable and clearly structured.


The use of JavaScript has been kept to an absolute minimum. Where it is used then all pages and processes are still accessible should JavaScript be turned off.
