Checking that Mahara meets current guidelines in accessibility as described in http://www.w3.org/TR/WCAG10/. Ideally we would like to meet standard AAA for everything, but we should at least meet standard A for things.
The is will be a good place to list what currently passes and what fails to meet the guidelines, and which guidelines we will be testing against.
