Manage who can join and invite

{!admin-only.md!}

By default, users need an invitation to join. You can additionally allow only administrators to send invitations.

Alternatively, you can allow anyone to join without an invitation. In this case, you can also disallow disposable email addresses, or restrict new users to a list of email domains (e.g. corp.example.com, or *.example.com).

{settings_tab|organization-permissions}

1. Under Joining the organization, configure Are invitations required for joining the organization.

2. Under Joining the organization, configure Restrict email domains of new users.
