CodeIgniter 2.0.2 CAPTCHA help / Tutorial?

[eluser]kdawson[/eluser]
Hi All,
I'm very new to CodeIgniter and must say that I am very happy with it, mid way through my first application.

If I could just figure out how to get the captcha going, I'd be well on my way.

I have searched around and I find lots for the older version. I can see the similarities, but really could use a walk through.


Does anyone know of a good tutorial that can walk a guy like me , step by step, through the process of getting it going and validating?

Thank you.

Regards.
Ken
