Cyca/Communities/How a community works
What it is
The first question when you create a community is what kind it is, because the form changes after that. A study group should not be asked for a registration address; a school should not be asked to pretend it is a group chat.
You choose one when you create it. Nothing here is cosmetic — each one decides which fields you are asked for and what the community looks like to someone who finds it.
Every community is a room: messages, voice notes, photos, calls — the same conversation surface as the rest of Cyca, because it is the rest of Cyca.
A school or a large organisation can hold more rooms inside it. Class 8 is a room. So is the staff room, or a project, or a year group. Each one has its own members, its own count, and its own person in charge.
Visibility is a switch, not a type. The default follows the type you picked, and you can change it.
Search reads names and descriptions. A private community's invite code is never returned in a search result — it would walk straight past the door the owner closed.
