This plugin utilizes reCAPTCHA to help your blog stay clear of spam-registrations.
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 BuddyPress Template Pack. It makes a normal WordPress-Template ready for use with BuddyPress. The missing files in the template will be added.
Notice: The installation of this plugin will require additional work. Edit the ‘bp-recaptcha.php’ file to make your settings.
