A Memories Timeline gives you the ability to make the Timeline available by invitation only or it could be made public so anyone could view or add content/contribute.
Each time you 'Create a Timeline' you'll be able to change the privacy settings of that particular Timeline, click 'My Timelines' at the top menu and click "Start a Timeline" to start creating your Timeline.
Enter appropriate details of the Timeline you wish to create.
Turning this setting on and off will determine if users can find and contribute to your Memories Timeline.
