API Keys
To use reCAPTCHA, you need to sign up for API keys for your site. The keys are unique to the domain or domains you specify, and their respective sub-domains. Specifying more than one domain could come in handy in the case that you serve your website from multiple top level domains (for example: yoursite.com, yoursite.net).
Note: Replace YOUR_PUBLIC_KEY with one you got from google.
