Subject: Updated "Inaccessibility of CAPTCHA" draft published for wide review

Dear Colleagues:

The Accessible Platform Architectures (APA) Working Group, with the strong assistance of its Research Questions Task Force (RQTF) has published an updated
draft of "Inaccessibility of CAPTCHA." This newly revised and updated draft is available here:


We request wide review of this draft by 24 March. If reviewer comments indicate there are still issues with this draft, we will continue editing. On the
other hand, if we have sufficiently addressed current issues with CAPTCHA related approaches used on the web today in the view of the preponderance of
our reviewers, we will proceed to release this draft as Version 2.0 of a document first published as a W3C Note in 2005. It is for this reason that we
ask you to read this document carefully and respond with your view by 24March.

Further details about this publication, including specific questions we would like reviewers to address, together with instructions for responding are
provided in a blog post available here:


Please feel free to circulate this request and our draft widely.

Thanking you in advance for your time and consideration on behalf of RQTF and APA,

Janina Sajka,
APA Chair
