One of my more regular haunts, Accessify Forum, is currently being redesigned. You can see the requirements for the new system, as well as contribute to the process.
For those that don’t know, Accessify Forum is an invaluable forum for discussing accessibility. It has over 7,000 members with over 60,000 posts in the past 5 years. It is an essential starting place for web designers and developers wanting to learn more about accessibility, as well as anyone wanting to perfect their knowledge of the subject.
If you’re already a member, head on over there and give your input on how you’d like to see it improved. If you’re not a member, head over there anyway and browse the forums – you’re bound to learn something new!
