This package adds the support of captchas on spam-prone forms on a given Plone instance. Currently this package extends the user registration form from the package plone.app.users with the support for captcha views following the format found in collective.captcha. A compatible package must be installed before the captcha will function.
This package requires and is for Plone 4 or later. Plone 3.x does not depend on plone.app.users for the user registration form. To add the support for captchas on the form for those versions of Plone are done using the ZMI using the TTW editor on the registration template and script files.
You can install pmr2.cpatcha using buildout by adding an entry for this package in both eggs and zcml sections.
Example:
[buildout]
...
[instance]

pmr2.captcha

Once the site is rebuilt, start the instance and install this product using the Add-ons panel in Site Setup.
