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