reCAPTCHA Module for Drupal

First time I heard about reCAPTHCA (Blognone entry), I thought it's very brilliant idea. Protect your site from spam comments and benefit whole humanity in the same click, never know cool thing like this. Only one barrier that keeps me out of using it is no convenient module for Drupal.

Now, that barrier is gone. Someone has been contributed reCAPTCHA module for Drupal already. All you need to do is:

1. Installing normal CAPTCHA module
2. Installing reCAPTCHA module, as one method for CAPTCHA module
3. Register yourself at reCAPTCHA web site and get both public and private keys for your domain
4. Config CAPTCHA module in Drupal admin interface to use reCAPTCHA method instead of text or image method

So it's your turn, experience reCAPTCHA by commenting on this post!
