PunBB 1.3 official extension

General idea

You should use this extension in case you want to limit registrations of new users on your forum. With pun_invitation_only extension new members can register only in case you send them an invitation letter with the hyperlink containing unique invitation code.

Invitation code can be used only once. After being used it becomes invalid. Invitation letters can be send by forum administrator or by the groups of users, to whom administrator gives a permission to invite new members.
