I have long been away from these forums. If I recall correctly, I used to login from my Google account. Still, my Google account seems to be no more tied to my original MathOverflow account http://mathoverflow.net/users/828/andrea-ferrettihttps://mathoverflow.net/users/828/andrea-ferretti
Is there a way to prove that I am actually Andrea Ferretti and regain access to my account?
