e11 reCAPTCHA is a no-frills way to add Google’s reCAPTCHA widget to the standard WordPress comment form and/or the user registration page. By default it will require only logged-out users to solve CAPTCHAs on comments and new users to solve a CAPTCHA to successfully register on the site; it’s also possible to configure e11 reCAPTCHA to not require CAPTCHA solving in either of these two forms or to require it on comments by all users.
