This site uses Drupal 7, which has the following accessibility statement:
As an inclusive community, we are committed to making sure that Drupal is an accessible tool for building websites that can also be accessed by people with disabilities.
This initiative started with advancements with Drupal 7 accessibility. We have committed to ensuring that all features of Drupal core conform with the World Wide Web Consortium (W3C) guidelines: WCAG 2.0 and ATAG 2.0. Where possible, we will also update the previous version of Drupal core, version 6, to enhance its accessibility.

What is Web Accessibility?
Web Accessibility means building and maintaining website that are accessible to the entire community, through better development and maintenance practices that make it easier for every customer to access your services. Today litigation over accessibility is a common occurrence, with ever-stronger legislation in Australia, the UK, US and EU.
Who is affected by Web Accessibility?
Every visitor to a website benefits from a more usable and more accessible website, but for some users, websites built without accessibility standards in mind are unusable, and illegal. Such groups of users include:
The growing ageing population
Users with anti-virus/anti-spyware software or older software/hardware
Users with vision or motor disabilities
