The Alliance Political Center is where you can create an alliance or view information about any alliance.
If you are a System Leader, you can join your solar system into an existing alliance, using the password
you obtain from that alliance's leader.
Once you join an alliance, you cannot join another one for at least 6 hours,
although you can leave one any time.
If you are an Alliance Leader, you can enter your Alliance Control Center from here.
If your alliance has at least 2 systems in it, then you can enter the Alliance Leader's Forum from here, also.
