What do you mean "don't show in the user list so they were deleted"? Shouldn't that be the other way around? What are your criteria for deleting usernames? I definitely don't fall into the categories "CR Backup Admin" has mentioned. I can still search for my old posts. Yes, I'm the 100th person to register for this forum after the reformat. But I was already very active even before there was even a forum and we all just commented below the actual article. That is why I chose that username, it was an in-joke during those times before there was a forum (old-timers here would know the "joke"

), same with my signature (another in-joke, used by another poster in an article comment thread then

).
