Hi folks

I really don't like the standard approach to CAPTCHAs, as provided by the CB CAPTCHA module. These CAPTCHAs create a barrier for many users - not just spambots. Even with audio versions , they create a particular barrier for users with disabilities.

This interesting article shows the effect of captchas on conversion rates; www.seomoz.org/blog/captchas-affect-on-conversion-rates

I'm looking to implement some of the alternative approaches to blocking spambots, as detailed in this article; www.simiusweb.com/news/2009_07_07_form_spam_prevention.htm

Ideally, I'd like to be able to ask a simple question where the answer would be well known to our target audience, but not known at all to a spambot, or to the rest of the world. Any registrations that don't have the right answer should be automatically rejected.

Is there any way I can implement a custom question validation within Community Builder?

Thanks in advance

Shane

I agree with Shane and usability concerns....

Looking for some better options with the CB Captcha... like regeneration and better documented "audio playback" options

Is there a way for a user to "regenerate" the captcha image if they cannot determine what is automatically rendered? Am I just missing that option in a parameter setting ?

I am on a joomla 1.5.23 site with CB Captcha version 2.4

Also - the audio playback is not working for me. I am only given the "click to externally play or download sound file" option - Is that normal? That doesn't seem very user friendly. And even if I do choose to save-n-play - the audio file plays the "army version" {{NATO phonetic alphabet}} of the letters generated in the captcha...

so for "fwzzca" - the audio file states "foxtrot whiskey zulu zulu charlie alpha". I would want to include some kind of instruction/documentation to the user about how to "decode" the "army-speak" {{ which is the NATO phonetic alphabet }}.

thanks

I can provide site and user access if needed.
