Google has officially rolled out its 'Undo Send' feature to Gmail, although it's been available for experimental use for the past six years. You can choose the time window in which you have to unsend an email in your settings by selecting either 5, 10, 20 or 30 seconds. Thirty-one seconds and you'll have to hack the recipient's account to prevent your rant from being read. I have already unsent so many emails over the years. Usually when I'm mad at someone I write a really scathing email telling them how I feel then pound the send button. Then quickly unsend it. Typically the act of hitting send alone is cathartic enough to let my anger pass, and I can move on with my life. Of course several times p0rn pop-ups have frozen my browser and those emails did end up being sent, and now those people don't talk to me. *shrug* Everything happens for a reason. "It sounds like a lot of things happen because you're a dumbass." That is a reason.
Thanks to everyone who sent this, who probably regret the tip line not have an unsend button since none of you are getting personal credit. Don't be spiteful.
