verification

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！

Dear user, You are not supposed to create more than one account. We can delete the first account for you, you can then verify the second account with your school's email address. Which user account do you want us to delete?

You can change your email address using this link: https://grand-challenge.org/accounts/email/, you can't change your user name.

Wih kind regards,

The account I want to cancel is the one I am talking to you about now, and the login name is "柑橘乌云". Then I will use the school email to verify another account. Thank you very much for your help
