I have a GMail account (firstname.lastname@example.org) and I always log in with this account on Stack Overflow.
Now,I was forbidden to use this email@example.com account but I can use new account(firstname.lastname@example.org) .
I treasure my reputations and badges on Stack Overflow.
Therefore, when I use Stack Overflow, I want to get my reputations of email@example.com by logging in with firstname.lastname@example.org.
Can I change login account on Stack Overflow?
