Only the guild leader can invite new members to join the guild. To do this, click on the “men” icon on the "Guild" tab. A window with a list of players will open; here you need to choose who you want to send the invitation to. By default, the list includes the players with the most guild points. You can narrow your search for the player you want by name and level.
The leader can send out a maximum of 20 invitations at a time. If more are sent, the oldest invitations will be deleted automatically. If the player does not respond to the invitation within a month, it will be removed.
