We've got captcha

smallCaptchaSpaceWithRoughAlpha.pngThis past weekend, we added a captcha system to TED.com's "Send this user an email" feature. We're using reCaptcha, which harnesses the mighty power of captcha to help digitize old books and newspapers. Right now, reCaptcha is decoding texts from the Internet Archive (watch Brewster Kahle talk about the Internet Archive on TED.com).

We take our users' privacy and security really seriously. If you've gotten unwelcome email or spam through the TED.com member email system, please forward the whole email to me, including the header information with the date, to contact@ted.com.
