Dear Grand Challenge: Question 1: Now I have created two accounts, and the first account has been verified by the school's email address. I don't want the first account anymore, but I want to use the school's email address to verify the second account. Could you help me unbind my email address? Question 2: How do I change the user name and email address? Thank you！
