Basically, you can turn on a setting that makes you solve a few math problems if you're trying to send an email late at night. Like a captcha, but WAY MORE AWESOME. Anyway, I just activated it, and set it so that I always have to solve math problems to send email. Actually, I set it it up so that I have to solve math problems between the hours of noon and 4am because YOU NEVER KNOW WHEN I MIGHT BE DRUNK.
