Can we be sure our stories pass onto future generations?

For example, if you publish a story as 'private' it will not pass on to future family.

We recommend you give access to all your contacts or to groups within your family if you would like your story to be passed on. Contact lists and groups can, with your permission, be managed by future generations. So as your family grows, your contact list and groups will too. And new generations will gain access to your stories.
