It looks like SO lost my login information that it usually defaults me when I open SO Page to and gives me "1st time user" banner. Since I don't remember my old login information had to create a new account with no badges and no questions asked or answered. What should I do to restore old login information?
Do you remember your profile page?
If not, Are you in this list?
If not, do you remember some of your questions or answers? If yes, search some in stackoverflow search or search in google with site:stackoverflow.com
Once you found it, send email to email@example.com to get support to get your profile merge with new account.
