Help reCAPTCHA virtuemart integration

[Bob]

Hi,

I have downloaded the Joomla pluggin http://code.google.com/p/joomla-recaptcha/
, and have been able to get the captcha to show up on the virtuemart
registration page.

Can someone let me know where to put the verify catcha code ?

To get the captcha to show up in the registration page I used echo
'ReCaptcha::get('html')';

What function to use to validate the captcha and which page to put the
code ?

Thanks,
Bob
