Problem updating email

Hello, I don’t know in which category to post this so here it is.

My email address is no longer in use, but when I try to change my email address I need a password.
Since I log in via facebook, there is no password.
If I click “Forget your password?” it asks for an email, which is no longer in use.

So how can I change my email please ?

Thank you

PM me your old account, old and new email address. I’ll do the change, and you’ll just have to do “forget my password” again
