This new little app in Google’s Lab, blocks you from yourself to prevent you from sending mail you didn’t mean. You set a time for this feature to be on in your gmail account (default is between 10:00 PM and 4:00 AM on Friday and Saturday) and it will give you 5 math problems). If you are finding yourself too impaired to answer the questions in the alloted time, then you do not gain access to your email.
This is a great idea for anyone who finds themselves doing things they wish they never did in those night an weekend hours. Now can we get this for the car please?
