Plone Captchas (4.1)
quintagroup.plonecaptchas is a simple captchas implementation for Plone, designed for validation of human input in insecure forms. This is a standalone implementation which does not depend on captchas.net services.
quintagroup.plonecaptchas adds captcha support to Plone, it works together with quintagroup.captcha.core package (http://projects.quintagroup.com/products/wiki/quintagroup.captcha.core) and quintagroup.formlib.captcha (http://projects.quintagroup.com/products/wiki/quintagroup.formlib.captcha)
With these products installed captchas will be added to Plone's 'Send this', 'Contact Us' (/contact-info) forms, and Plone's default discussion mechanism: 'Add Comment' and 'Reply' forms.
quintagroup.plonecaptchas does not automatically plug to Plone's default registration (/@@register). You can make captcha plug to Plone's Register form via Zope Management Interface. Instructions here: http://projects.quintagroup.com/products/wiki/quintagroup.plonecaptchas#JoinForm
