Since there is a "Captcha - ReCaptcha" plugin for Joomla!2.5, I wonder if somewhere in the back-end has such setting for VM2.0 "Ask a question about this product" or anyway to carry out the same. It will definitely prevent spam messages.
Anyone could help out? Thanks in advance.
I would like to know if this is available too. This is a needed feature.
I use comercial version of Joo ReCaptcha (http://extensions.joomla.org/extensions/access-a-security/site-security/captcha/14109) for five month and the results is good, no more spam registration and questions.
