Implemented new captcha based anti-spam system
I’ve implemented a far improved captcha anti-spam system. This new system uses captcha’s from http://recaptcha.net/. There are a couple great things about this system. First, the captchas go to a good cause. Every time you fill one of these captchas out, you’re helping to digitize a book for the internet Archive or old editions of the New York Times. Second, the captchas are known secure, because the words submitted to the system are those that failed OCR by the high end production systems that are digitizing these books. Third, the captcha is very user friendly with both the ability to hear the puzzle (for the diabled) and the ability to easily aquire a new puzzle if the one you’re looking at is garbage.
