# Registration modes

Let anyone join, review every application, or let in only certain people.

-   Pick open sign-up, staff approval, an email domain allowlist or closed sign-up.
-   Turn user invitations on or off.
-   If invitations are on, people can still join a closed server with an invitation link.

The Registration tab covers approval, invitations, CAPTCHA, and closing sign-ups automatically when nobody on staff uses the server.
