Recently one of my colleagues was talking about this new feature in GMail.
Apparently it existed since October 2008, but I only heard about it yesterday.
What it does?
It prevents you from sending an email when you are drunk, there by helping you stop sending email that you would regret later.
Yes, if you enable this feature, whenever you send email on late hours, GMail would ask you to solve a math question.
If you do not answer it right, your email will not be sent and will just end up in the Drafts section.
What is on your wishlist? what do you want your GMail to do?
