Is ReCAPTCHA required?
No. ReCAPTCHA is not required to use Comment Guard Pro. However we do provide a way to integrate ReCAPTCHA, should you so desire, in Are you Human pluglet. CAPTCHA technology is used only for Javascript disabled browsers which comprise a negligible portion of viewers on any site. When you enable ReCAPTCHA, it will then replace the in-built CAPTCHA support. You can freely sign up (and use) your blog(s) for ReCAPTCHA. When you sign-up your blog you will be provided with a public & private key which you should provide in Are you human pluglet configuration to enable ReCAPTCHA instead of the default CAPTCHA service. To re-iterate any form of CAPTCHA is used only as a backup, most of your readers will never know that it exists.
