It's Sunday morning, you flip open your laptop and settle into your desk, downing a few aspirin and a cup of coffee to recover from last night. You login to your e-mail program, and notice some very strange replies from your colleagues in your inbox. You check your Sent Mail box and your stomach starts to pitch - an e-mail, to all of your colleagues, sent to your colleagues (and boss!) after a night out with friends. Fear no more! Gmail unveiled a new feature this morning, Mail Goggles.

Mail Goggles is a feature that you can turn on (default settings are Friday and Saturday nights) that forces you to complete simple math problems before sending an e-mail. The standard preset is to automatically turn on Friday and Saturday nights, but you can adjust this to whenever. So for all you Gmail users, fear those drunken e-mails no more! As far as drunk dials and texts though, you're on your own.
