Remote Gmail Log out

We know you have all done it.....Forgot to sign out of your Google Account on some random computer.  Now you do not have to sprint back to that one computer and log out, with a simple click you can log out of your Google Gmail session if you've forgotten to log out. Simply log on at your new location and click 'details' at the very bottom of an old email and then click lo'sign out all other web sessions'.  Once you have done that, Crisis adverted!
