If you forgot your password to log into your TNG website, all is not lost. Go to the home page and click on the “login” link. That will show a pop-up window for normal logging in. Note the last choice of: “Enter your e-mail above and your username below to have your password reset (a temporary password will be sent to you).”
So add your email address and your Username into the boxes. Then your TNG site will send you a temporary login to get you going. Don’t forget to change the temporary password to a more familiar one.
