IMPORTANT: Some M+Google non-core services (such as Google+ or YouTube) have minimum age requirements (13 in most cases) as part of their Terms of Service. If you are prompted upon sign up to supply your birth date to confirm your age, DO NOT enter a year that makes you below that age. Doing so will automatically lock you out of your account. U-M administrators are not able to override this lockout and you will need to re-activate your account directly through Google. More info here.
