[HAN University of Applied Sciences](www.han.nl) kindly did an
accessibility test of the mCaptcha widget and the showcase site, which
features a real world integration of mCaptcha in a third-party service.
The report motived us to make screen reader testing an integral part of
the release process.

Here are the results:
