The server administrator can disallow registration without invites. The ability to create new invites can be limited or disabled for the given user. One can see who invited the user (this is public information).
The config.invitations section was added with two fields: requiredForSignUp (boolean, false by default) and canCreateIf (array of conditions, empty by default).
If config.invitations.requiredForSignUp is true, then:
Registration without invites is not allowed;
Multi-use invites are not not allowed.
