The WAI-AGE Project (Ageing Education and Harmonisation) focuses on education and outreach regarding the requirements of people with Web accessibility needs related to ageing. One of the WAI-AGE project deliverables is Web Accessibility for Older Users: A Literature Review, which was published on 14 March as a First Public Working Draft. WAI encourages you to review this draft and submit any comments by 4 June 2008, if possible.
See Call for Review and Participation: WAI-AGE Literature Review and Task Force for an introduction to the project and an invitation to contribute to the literature review and other WAI-AGE work. (2008-05-14)
