Could you add component properties something like:
OnReCaptchaSuccess
OnReCaptchaFailure
Where the programmer can assign callback procs for each?
Right now I have to add a non-intuitive button on the same form to move to the next stage after the user successfully solves the ReCaptcha. I think most end-users expect something to happen automatically when they solve the Captcha.
I am not sure that my suggested OnReCaptchaFailure property is actually needed, since the component already loops until you enter the correct text.
