Chats

A chat can be either a parent or a child chat.
Chats are by default parents. A single chat is also a parent chat.
A child chat is "owned" by another chat (the parent).
Child chats have no users of their own but instead inherit them from their parent.
This extends only to 1 level. The longest relationship is parent->child, not parent->child->grandchild or further.
A parent chat can have unlimited children, but a child chat only has one parent.

A user can be either a parent or a child user.
Users are by default parents. A single user is also a parent user.
Only global users can be parents, but both global and local users can be children.
A child user is "owned" by another user (the parent).
Child users have no password or email of their own but instead inherit those from their parent. What else should be inherited is yet to be finalized.
This extends only to 1 level. The longest relationship is parent->child, not parent->child->grandchild or further.
A parent user can have unlimited children, but a child user only has one parent.

A user can be either global or local.
Global users count as "registered" in all chats that honor global users.
Local users are registered in only one chat and all children of that chat.
Chat Masters have direct control over all local users of the chat, including deleting them and resetting their password, email, editing their profile, etc.
Chat Masters have very limited control over global users, such as setting chat-specific flags, etc.
