<p>This Plugin integrates the Google reCAPTCHA Service Modul in the BuddyPress Template Page ‘register.php’. The file is located in ‘/wp-content/themes/{name}/registration/register.php’. The plugin adds the new feature by adding an action on ‘bp_before_registration_submit_buttons’. Therefore the ‘register.php’ must contain the line ‘do_action( ‘bp_before_registration_submit_buttons’ )’. My one was generated with the famous plugin <a href="https://wordpress.org/extend/plugins/bp-template-pack/" rel="ugc">BuddyPress Template Pack</a>. It makes a normal WordPress-Template ready for use with <a href="https://wordpress.org/extend/plugins/buddypress/" rel="ugc">BuddyPress</a>. The missing files in the template will be added.</p>
<h4>Some Features</h4>
<ul>
<li>not yet, the plugin has no admin-page, but it will follow</li>
<li>at the beginning of the ‘bp-recaptcha.php’ are some variables to add/change the <a href="https://www.google.com/recaptcha/admin/create" rel="nofollow ugc">reCAPTCHA Api keys</a>, style of reCAPTCHA, language and texts</li>
</ul>
<h4>Languages</h4>
<ul>
<li>English, but can be switched very simple</li>
</ul>
<p>Notice: The installation of this plugin will require additional work. Edit the ‘bp-recaptcha.php’ file to make your settings.</p>

<p>This plugin is just a very effective yet simple plugin which adds a question to the comment form that blocks most automated spam-bots by making them answer a common sense question. For optimal effectiveness, you should add multiple questions so that the spambots can’t “memorize” the question and answer. The plugin will display questions at random to prevent the aformentioned memorization. Multiple answers can be added per question to account for variances in answers. (e.g. “five”, “Five”, “5”)</p>
