What types of Memory are there?

Any Popster can create Memories, which come in three modes:

Type	How it works
Public Memory	Freely viewable by all Popsters. Once you follow it, you start seeing the Pops (moments) added to it.
Personal Memory	Seen and edited exclusively by the Popster who created it. It works as a collection only you can view and access.
Private Memory	Restricted, and depends on approval from the Popster who created it before another user can follow it and view the content.

Only for Public Memories and Private Memories can Administrators and Collaborators be appointed by the Popster who created it.
