When the new version of iOS comes out Apple will introduce “Family Share.” The way it will work is everyone who has the same credit card associated with their iTune account will be able to share their media purchases.
I think this would be a great idea for Logos as well. I realize my wife can use my email and password to use my library on her computer, but every layout and document she creates and modifies changes my documents. Moreover, if Logos really wants Faithlife to take off each member of the family need their own account and profile, to share an account kind of defeats the whole social media thing Logos is trying to create.
