We are currently using ReCaptcha on our website (developed with Ruby on Rails)which we think is coming in the way of our users (see here: http://www.pakwheels.com/used-cars/add_car).

We want an easier Captcha, perhaps something which is simpler (3 or 4 letters or numerals). Please see the attached screen shot for example of something which i want.

NOTE: please note that the plugin should work on an Ruby on Rails website

I think you can define the amount of characters the user will need to type in with the code easy.

i independently found the same captcha from my google search, but seeing that someone else has recommended the same gave some reassurance.
