Groups
A group is a shared place for memories. Everyone in the group can read and write there. Groups are optional — personal memory works on its own.

└── groups[] shared spaces you belong to
This is not the same as User Groups under System Settings (Administrators / Users). Those control who may sign in as an administrator. Memory groups are only about sharing entries and guides.
Creating and belonging
Any signed-in user can create a group from the web UI (or via a connected agent).
The creator owns the group: invite or remove people, rename it, and delete it. Deleting a group also deletes the memories in it.
Other members can use the group’s memories, leave the group, and otherwise cannot manage the roster or delete the group.
There is no separate viewer / editor ladder beyond creator vs everyone else.
The creator cannot be removed from the roster.
An admin account can manage groups across the site when needed. Everyday use should be your own user account.
Where new memories go
When you (or an agent) save a memory, you choose a destination:
A specific group you belong to, or
Your default shared group (if you set one), or
Otherwise your personal space.
Each memory lives in exactly one space. Who can see it is whoever belongs to that space.
