Thanks for the reply. I don't own either. I do own the Super Suite, and the User Registration solution. I know that the User Registration solution has a CAPTCHA in it. I thought it was created with extensions within the Super Suite.
Just as an FYI, reCAPTCHA is the latest from the creators of the original CAPTCHA from Carnegie Mellon University recaptcha.net/. At least that's how I understand it. I'm not really a big fan of the interface so I don't mind trying something different.
