Subject: 48-Hour Call for Consensus (CfC): Publish Second CAPTCHA Wide Review Draft


This is a Call for Consensus (CfC) to the Accessible Platform Architectures (APA) Working Group seeking consensus to publish the "Inaccessibility of CAPTCHA" document for a second, and we hope final, wide review.

The draft to review for this CfC is here:

This draft has undergone yet more extensive revision since our first wide review was published early this calendar year. We received numerous excellent comments all of which we believe we have now addressed. Of course, the additional comments received required our Research Questions Task Force to think even more deeply about the meaning and current implementations of CAPTCHA Turing Tests. Thanks to the many individuals who have provided substantive and editorial assistance in this effort.
If your name isn't listed, please advise--because we intend to thank you formally in the publication.

Please note that no substantive nor editorial changes will be applied during the CfC to the above URI. However, editorial work is likely to continue on the Editor's Draft which can be found here:


This CfC is now open for objection, comment, as well as statements of support via email. Silence will be interpreted as support, though messages of support are certainly welcome.

We particularly welcome questions and suggested edits, though this could delay publication. It's important we get this draft right.

If you object to this proposed action, or have comments concerning this proposal, please respond by replying on list to this message no later than 23:59 (Midnight) Boston Time, Thursday 23 May.

NOTE: This Call for Consensus is being conducted in accordance with the APA Decision Policy published at:

Thanks again to everyone who's worked to update this important document.
