I belong to a book club, and several of us would like to share books using our i pads. From the research I have done, it seems that the only way to do it is to sign out of one's iTunes account, and allow somebody else to sign into your account, and then download the book. Is that the only way to do it. We have 5 people in our sharing group. I would appreciate somebody telling me the easiest way to accomplish this. Thank you.
