I think all of them are reading this thread and laughing their asses off because the album is already finished,
I may disappoint you there... normally, I surf in inprivate until I have something to say; then I log in. Normally when I'm on inprivate, there is only 1 Hidden. Not saying that no one else does that, but it was likely me.
However, I could be wrong... our hidden guest(s) might be one of the guys too.
