The Athenian hoplites is active and always looking for new members. and the thursday public (open to all) shieldbattle is still running. Join the Steam group to get announcements! We are hopefully looking to get some larger events as well.
Well, you could first of all tell about it to your friends and get them to play this. and try to get your clanmates and friends from other mods to try this aswell and inform them about events. You could also found a clan with friends and try to get people to join it and this mod.
