I have set all of my privacy settings to NOT allow any followers to follow my profile and have disabled most visible settings and made all of my idea books private. I would like to share my idea books with a select few people (close friends and family, and my architect and builder). If I add these people as friends, will they be able to view my idea books, or will I have to collaborate by adding each person to each idea book for them to view (not edit) my idea books?
