The Free-ARIA mailing list is for developers and testers contributing to the development of free WAI-ARIA tools and resources. The purpose of WAI-ARIA is to provide a means to address Web 2.0 and AJAX accessibility.
Some of the free stuff already being worked on:
- Testing tools for authors
- Training materials
- Assistive technologies such as screen readers
Feel free to join if you want to be part of the larger WAI-ARIA community effort.
There is also an IRC channel for WAI-ARIA questions — irc.w3.org:6665 #wai-aria.
