Protect login and registration with a skimpyGimpy CAPTCHA
The CaptchaAuthPlusPlugin puts a skimpyGimpy CAPTCHA on the registration page to protect from unwanted bots. It also puts a captcha on the login after 3 failed login attempts. Requires the AccountManagerPlugin. The registration captcha requires AccountManager's registration module to be enabled.
You can choose to disable registration captcha or login captcha by enabling or disabling their respective plugins.
This plugin is based on CaptchaAuthPlugin but does not depend on it.
