If you input an incorrect birthdate -- one that indicates you are under age 13 but actually are older -- you will still have to go through the AgeCheq procedure. We cannot (legally nor technically) change your birthdate after it's been input on your computer or mobile device.
After completing that process and registering your account, you will not have text chat enabled in public games. We can unlock that if you email us with proof of age (ID with name and age, birthdate, or grade).
