The reCAPTCHA MediaWiki plugin uses a CAPTCHA to prevent spam. Here is how to add reCAPTCHA to MediaWiki:
Download the zip file (note that this plugin only works with MediaWiki 1.8 or newer).
Unzip the MediaWiki extension.
cd /path/to/mediawiki/extensions/ # * gets whatever version you downloaded unzip ~/recaptcha-mediawiki-*.zip # move the package to a standardized directory. mv recaptcha-mediawiki-* recaptcha
Add the following lines to MediaWiki's LocalSettings.php:
require_once( "$IP/extensions/recaptcha/ReCaptcha.php" ); // Sign up for these at https://www.google.com/recaptcha/admin#createsite $recaptcha_public_key = ''; $recaptcha_private_key = '';
Enter the public and private keys in LocalSettings.php. (If you haven't done so, you must sign up for reCAPTCHA keys here.)
That's it! You should have CAPTCHAs now!
