This plugin has a bug that makes it fail on some servers, though it works perfectly on other servers, keep frosty if you try to use it!
Recaptcha (http://recaptcha.net) is a image verification protocol which both provides us with image verification and simultaniously transcribes old books.
Upload all files and folders to /path/to/cnr/plugins, enable plugin through options > manage plugins, use {recaptcha} to display the recaptcha verification.
If you are familiar with recaptcha, and want to use your own, non global, keys, please edit the keys in recaptcha.php.
You can test an implementation of the plugin here: http://thunemedia.no/recaptcha-demo.php
Enjoy![/b]
