I originally used an email trick to allow my sister's kids to message each other, but stay under the same apple id. I originally setup some email alias's with comcast i.e.....the main address was <email@example.com>, the kids iPads address for FaceTime and iMessage was <firstname.lastname@example.org>, <email@example.com>, but they were under the same apple id. But they are now older and have out grown this, they need their own apple id's for games, etc..... Now I want the <firstname.lastname@example.org> and <email@example.com> to be their own apple id's. The thing is they are associated and have been verified with the old apple id. Can I just use these extra email addresses to create new apple id's and put them in a family plan. Any suggestions would be appreciated, this gets very confusing for me and hard to manage.
