I already have an account on Stack Overflow, and have a guest account on Code Review.

I want to know if and how I can merge these two accounts. Any ideas?

    Go to the contact us, select the "I need to merge user profiles" and follow the instructions.

If you sign into your Code Review account using the same OpenID as you used for your Stack Overflow account the system should automatically link the two accounts.


I have heard that if credentials are the same between two accounts, the system may automatically merge them without human intervention. It was mentioned on the comments on this question, but I do not know the criteria behind that.


You can't do it, only a diamond mod can. You can go to the contact us link at the bottom of the page and submit a ticket explaining the circumstances.
