How do you use Recaptcha in Joomla?

From Joomla! Documentation

The link to the Google Create Public keys is broken.

Hmm, it takes me to the sign up page. Well, the landing page describing reCaptcha with a link for sign up.

Also, this instruction is not complete. It enables the ReCaptcha in Joomla and publishes the object on the page, but it does not actually create the input box. I would update this page, but since it is the instruction on how to do it, I don't know how to do this.

I just tested this with 3.x on a vanilla Joomla! installation, reCaptcha works for me. Could you give more details? Thanks Tom Hutchison (talk) 21:30, 22 April 2014 (CDT)
