Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello,

I have a little problem, I created my account at the beginning of Nostalrius with an old email address and now I can't access to this email address anymore.

Can I send a ticket to the staff or something to ask to change my email address please ?
Or is there a way to change it ?

I really hope there is a chance to change my email because for now I'm stuck with this old inaccessible email.

Thank you in advance !
