Joining a Squad
Open /squad, choose Join and enter the squad code. This sends a join request; it does not bypass the leader's approval.
You must be from the squad's village, the squad must have room, you cannot already be in another squad and your 6-hour squad-change cooldown must be over. A squad that is recruiting for or running an expedition temporarily locks membership changes.
Join requests expire after 24 hours. If yours expires or is rejected, you can send another request when the normal conditions allow it.
