Did you see the answer 12 years ago from the site's CEO suggesting that the original poster consider joining www.chesskid.com, which does offer a family membership?
Yes, but I'm not a kid nor parent nor teacher.
Chess.com needs to offer a Family Membership. It is a reasonable request. I will not spend money with them until they do this.
Come all apps got Family membership ..I have 3 teens chess players an me and my wife... We need Family membership.
