<p><a href="https://wordpress.org/plugins/jetpack/" rel="ugc">Jetpack</a> makes it easy to add contact forms to your WordPress site, but you may want a simple way to add a <a href="https://www.google.com/recaptcha/" rel="nofollow ugc">Google reCAPTCHA</a> to prevent spam.  This plugin will manipulate the Jetpack <code>[contact-form]</code> shortcode to prepend the Google script, add a button, and parse the response.</p>
<p>This plugin allows both reCAPTCHA v2 and invisible reCAPTCHA (see screenshots and choose whatever works for you!).</p>
<p>Shoot me a question about it on Twitter: <a href="https://www.twitter.com/bozdoz/" rel="nofollow ugc">@bozdoz</a>.</p>
<p>This plugin is open source on <a href="https://github.com/bozdoz/wp-plugin-recaptcha-jetpack" rel="nofollow ugc">GitHub</a>!</p>

<p><a href="http://jetpack.me/" rel="nofollow ugc">Jetpack</a> is an awesome plugin bundle provided by the Automattic, but it requires WordPress.com account<br />
even for those modules previously work as independent plugins. The marketing banners are very obtrusive too.</p>
<p>I smashed the bundle to remove the annoying parts and keep the awesomeness. Slim Jetpack will track the updates of Jetpack modules,<br />
but is definitely INCOMPATIBLE with its original version because a lot of API functions had been mocked or removed.</p>
<p>All credit goes to original developers @<br />
<a href="https://wordpress.org/extend/plugins/jetpack/developers/" rel="ugc">Jetpack</a>!</p>
<p>SlimJetpack 2.1.1.x is corresponding to Jetpack 2.1.1 and the x is the bugfix mark.</p>
<p>If you find any bug, please submit a ticket here: https://github.com/HowardMei/slimjetpack/issues<br />
Or just fork the repository and send me pull requests 😉</p>
<p>Please deactivate Slim Jetpack and use the original Jetpack instead if you need the wordpress.com likes/stats,<br />
subscription and push notification services etc.,</p>
