A wiki belongs to one owner and can be shared with other users at three levels of trust. Permission lives on the wiki itself — there's no per-page or per-block override.

## Roles

The owner is implicit and cannot be removed. Other members get one of three roles, ordered by growing capability.

### Viewer

Reads. Equivalent to anonymous browsing on a public wiki, but with access to a private one.

### Editor

Reads and writes content — pages and blocks. Cannot change wiki settings or manage other members.

### Admin

Everything an editor does, plus changes the wiki's title, visibility, and language, and manages members. The closest thing to a deputy owner.

## Adding and removing members

Open the gear icon (Manage) on the wiki. The Members section lists everyone with a role. Click "+ Add", search the user's display name, pick a role, confirm. To change a role later, click the current role next to the member and select a new one. "Remove" revokes their access entirely.

Users you invite must already have a Wikilayer account — email invites aren't supported yet.

## How visibility fits in

Permissions answer who can do what. Visibility ([Three flavors](page:3112)) answers who can see the wiki at all. A public wiki is readable by anyone, members or not; a private one is invisible outside the member list. Archive hides the wiki everywhere except the owner's `/manage`.
