With not a little experimentation I finally got CAPTCHA and reCAPTCHA to work on DonTai.com. CAPTCHA presents a test that humans can pass but spambots cannot. reCAPTCHA builds on CAPTCHA and rpesents the commenter with 2 words, which must be typed in. They are great to prevent spam. OpenID is another way to login. You set an account up, then add an OpenID to your account. Login to your OpenID authenticator, then login to dontai.com, type in your authenticator, and then you're approved. No more duplicate ID and password.
