Previously, I had two separate Stack Exchange accounts. One was work related, the other was for personal use. For some reason, StackExchange merged those two accounts as one. (I cannot recall or explain the reason why.)
So, I am concerned about the following:
Both my wife and I have our own StackExchange accounts, each registered to a different email address. Would these accounts be merged if we use the same network or computer? If so, how can we let StackExchange know that these accounts should be separate?
