Can you guys help me with CAPTCHA and accessibility on my site? I recently took over a site to help a friend. I have a programming and sysadmin background; I know Perl, Linux, AIX, etc, but not PHP/SQL as much. Of course this page is mostly in PHP, and the CAPTCHA script is pretty wild. I'm trying to make this site meet at least level A of the W3C rating for accessibility and the last piece is an alternative modality for CAPTCHA. Right now it's an image displaying the distorted letters. W3C recommends something like an audio playback that the user can respond to, or a form question that a text reader can work with, like asking "What's 3 + 6?" I'm leaning towards the form question for simplicity; Is there any easy way to add this functionality and just randomize a few questions/answers and still keep it secure? If I'm going the wrong direction here, what would you all recommend? Thanks for the help.
