Societies can be a group of friends or business men with mutual interest. It is entirely up to you. The choice of how a society will be ruled will be up to the creators. The founders of the society will be able to choose how they rule the society out of a selection. Yes there will be a feature in-game that will allow society members to speak directly to each other at all times.
Societies can make lands that they own community property.
When a society comes up with and designs a banner that they wish to use in-game they must send it to the designers of Project Entropia. They will look over the design and, if appropriate, incorporate it into the game. All rights reserved.
