As the title says.
I can't find it anywhere on clan.aeriagames.com/ava
right now we cannot create squads or appoint squad leaders but as the GM wrote in here: http://www.aeriagames.com/forums/en/viewtopic.php?t=1799807
they already started working on the development of this feature.
right now you can only appoint your members as "Staff" and they can then invite new members or kick the old ones if they need to.
