I have been using Stack Overflow with my Facebook account. However I deleted my account. By chance my current computer still had the account on. So registered into Facebook again with different e-mail address and changed my e-mail address on Stack Overflow.
Now, when I clicked to log in with Facebook, it gave me another ID, I changed my e-mail into Gmail, still gave another ID. I tried forgot my password option and entered the e-mail address, it could not find any e-mail address in the system. So what should I do to retrieve my account?
