My account has wrong email address and I can't login to fix it (of course)..

Hi, I don't know why it happens.. but my account has wrong email address (ychco379@gatech.edu) which doesn't exist.
My email address is ycho379@gatech.edu, so it should be a typo error, but I don't know how it happen although you checked email verification.
Anyway,, I can't login my account because I can't receive verification email.
Can you help me to change this email address to right one and I can login my account safely?

Best,
Yinseo
