I'm new too! Trying to be as helpful as I can be! I think when you fan someone the purpose is so that their auctions come up on your feed more often than people you are not fans of. Watching makes it so it is easy to find auctions that you are trying to keep up with. They have their own tab in your "my listia" once they have been watched. Hoping that helps and hope I win! I've bid nearly all my credits on this! Haha!
