There are several people who have more than one, panic. So do I, as a "safety net" after I was repeatedly "banned" for some unknown reason. When I came on with my second user name, it was so similar to this one that everyone knew me before I announced it! After emails from the Ed, I was allowed it, but reverted back to the original asap. I suspect this is the case with some others as well, but from personal chats I've had with people, it seems no one really likes those who hide behind multiple user names for the sake of it - and most become transparant anyway, as they slip back into their old way of speaking.
