can someone point me to how to add a co-manager, what they can see, how far back and forward they can see? i have two distant cousins here. i am the manager of one and added him as co-manager. he has correct or additional missing info forwards and backwards in his branch if he could edit them. if i add him again near the top, does he see everything below? (i rummaged around in general help but could not find what i am asking.)
