Mail Goggles

Mail you send late on Friday night or the weekends may be useful but you may regret it the next morning if you send email after a few to many drinks.

This new feature offered by Google Mail means you must solve some simple math problems before sending late night email. Otherwise if you cant solve the puzzle better get a good night's sleep and try again in the morning

This feature would certainly be useful for a certain Director at a company I used to work who was prone to send quite strongly worded emails to the LAN Support team, the emails were date stamped late at night late and contained a fair bit of blue air!
