if you introduce captchas on the OOOauthors-website, it is probably a good idea to use recaptchas.
Recaptchas are a sort of [EMAIL PROTECTED] concept for books.
By entering the captcha, you do something useful - quote:
"reCAPTCHA improves the process of digitizing books by sending words that cannot be
read by computers to the Web in the form of CAPTCHAs for humans to decipher."

How do they verify if you entered the correct word? A captcha is only
useful if the server can verify the answer.
