So, I'm a Drupal fanboy. Naturally. But there's been some amazing work recently by the Drupal Accessibility Team that I wanted to highlight.
Accessible CMS: Drupal!
According to Drupal's Statement on Accessibility:
This initiative started with advancements with Drupal 7 accessibility. We have committed to ensuring that all features of Drupal core conform with the Worldwide 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.
That's a pretty bold statement. Perhaps even more exciting is the Drupal Accessibility Pledge where the maintainers of the thousands and thousands of contributed modules and themes agree that they are willing to work to fix problems if those problems are brought to their attention.
But who can bring the problems to their attention?
CMS Accessibility Team: Groups.drupal.org
Drupal has a large team of accessibility professionals who coordinate their efforts on groups.drupal.org and in irc and other community methods. This group of 374 individuals has been working since 2006 to make Drupal core and it's modules/themes more accessible. The group has over forum threads and hundreds of comments discussing ideas on how to achieve this. It's truly amazing work.
As one of the folks who helps make groups.drupal.org function I'm always inspired when people point to that site as the home of their team.
