So the user who is both blind AND deaf? Or the blind user who is at a library computer with no audio output? I saw some research where out of four people with "normal" hearing, all four were unable to distinguish the crappy audio output into the correct word and use a site. Granted, a very small sample, and the audio from the test site may well have been at the low end of the spectrum for quality. But it was a real site, and these were just regular people roped in for a test of the audio's usefulness. As "cool" as CAPTCHA seems at first, I don't think it's going to be a long-term solution. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
