Ok, I have "this friend", see?
So anyways, "this friend" has his iTunes on computer A. He backs up the actual music folder - all of the songs - onto computer B
If I want to move my itunes software to computer B and manage my iPod from computer B, I have to "decertify" computer A, and that scares me.
So... what is the process for doing that - changing it so that computer B is my music library manage and the location that I manage my iPod from?
