Ok, so i changed my email address (sign in id) on my BN account. I used the computer to do it. How do I change it on my Nook Tablet? Is there a way to sign out of my account and then sign back in with the new email? Im able to buy and download books still on my nook, but if i go to the settings-device info-about your nook.. it still has my old email address and wont let me change it.. Any ideas??
