Greetings,
I can't resist the impulse to jump on my web accessibility soapbox at this
point and recommend that if you insist on using a visual captcha in your web
application, that you also provide an audio alternative to those using
assistive technology such as Apple's VoiceOver or JAWS from Freedom
Scientific.
Obviously screen reading technology is unable to read the graphics presented
in a visual captcha, making it very difficult for screen reader users to
register on your site.
Providing an audio alternative is not always practical, so listing an email
address on your signup form for people requiring some assistance with the
captcha is often a good compromise.
We are only talking about a very small percentage of users who are likely to
visit a given site, but it's still worth a couple of minutes to consider web
accessibility.
I'll keep it brief, but it goes with out saying there is a vast quantity of
information about web accessibility out there, just ask Google.
Cheers,
Mitch

Hi All,
Does anyone have a suggestion regarding a free captcha generator, that
works well with WO ? We wouldn't complain at all if there was some code
you could throw our way in regards to implementing it to. In fact we
woudl be most grateful.
Thanks
