This would be useful for fort wars. A simple gui where people can make a team. Then people can willingly join the team if the owner of the team has "Allow Others In" set to true. The host chooses if teams can attack their own team. Teams can join Alliances as well. An alliance is where multiple teams team up. The leader of team1 can send a Alliance treaty to the leader of team2 and he/she can either accept or decline it. If accepted, the teams get placed into a new Alliance. The leader of your team can pick a team name. The leader of you alliance can pick an alliance name. I will update soon.
