  Dear Webmaster,
 You're receiving this email because you're registered as a website
 administrator for a site that uses reCAPTCHA.
 Google launched reCAPTCHA v2 (i.e. No CAPTCHA reCAPTCHA) in Dec, 2014. The
 new version provides a more simplified user experience than reCAPTCHA v1,
 with an enhanced spam fighting mechanism.
 reCAPTCHA
 Action requested: please upgrade your site implementation to reCAPTCHA v2.
 Please refer to the developer guide for integration details. We hope you
 enjoy the new reCAPTCHA.
 Thank you,
 reCAPTCHA Support
