Radio Captcha
A trivial captcha that presents a human/robot choice as a radioset. Provided primarily as a convenience for testing forms.
Radio Captcha provides barely any security from robot form submissions whatsoever!
This addon was developed to assist with testing Form Reform during development and on stage sites, where a large number of forms needed to be tested deterministically with captcha pass and captcha fail. Traditional captchas were either too nefarious or just too much hassle to deterministically pass or fail. Hence Radio Captcha.
