Think about it . . .
What is a ghost? It's someone posting to more than one account.
Why would anyone do that?
Two reasons . . . one account is banned - or, they want to have a double voice. In this case, typically, the first account will say something, and the second account will say "I agree."
Obviously, SOUR is not the type to ever be banned - and just as obviously no account which posts as much as SOUR could reasonably be a second account (the "first" account would have to post even more).
To even suggest SOUR is a ghost is illogical and lazy. But, for those who are struggling with the basic rule of the forum (show respect) it's easy to attempt to discredit someone by calling them a name. But, when the name calling is unsubstantiated and illogical, it only serves to discredit the name-caller.
BTW, Tom Patterson made the effort to change SOUR's username . . . Tom's years of customer service background leads him to be more responsive to such requests - so don't be shy asking him for such small favors (whereas I put such requests into a pile of tasks that I plan on getting to when things are not quite so busy - a day that never seems to come!)
