[edit] Description

This plugin implements the ReCaptcha Captcha authentification.

Recaptcha is like regular captchas, but in contrast to regular captchas these are from scanned books and they already failed being recognized by a OCR, so according to the authors of recaptcha this method is far more effecive than "regular" captcha.

For details on ReCaptcha, please visit http://recaptcha.net].

[edit] reCAPTCHA API Key

You can obtain your recaptcha API Keys from recaptcha.org. Please note that it is only good for one domain including all subdomains.

If you host serveral blogs on different domains, you might want to let the blog owners enter their codes individually, and do not enter anything in the Administration Settings.

WARNING: If the code is entered in the Admin section, all blog users can see it! I still have to figure out how to avoid it. Please mail me hints/patches.

[edit] Configuration & Setup

In order to employ the plugin, do the following

1. Obtain your API Key at recaptcha.net
