Double A Conformance

Hi,

I'm a multimedia developer (I can do a bit of everything but always have to learn more to complete a task), I have experience in developing HTML, CSS, Javascript, Actionscript 2 moving to 3 now and a very brief understanding of PHP.

I've recently started learning how to implement Drupal as I have undertaken the development of a website for a public body that requires a CMS and they legally need the site to comply to WCAG Double A standards for site users but not contributors or adminstrators.
