The company have a lot of user groups.
In this section I'll explain what each group can do and what are the privileges of each:

1 - guest: a guest or a member that we don't know if is willing to stay on FC. This group have no privileges.
2 - Hatchling: base group of FC. This group have few privileges, like access to house and can use one of the chests.
3 - Whelp: a group where the players that participate on statics or FC events will stay. They'll have some bonus (to decide in a near future).
4 - This group is made of people that helps on the FC in a way (can be with crafting, gil, missions, furniture, and other ways). They have some privileges, similar to Whelp.
5 - Dragoon: in this group, there are people who can invite to FC and have all Whelp privileges.
6 - Elite Dragon: In this group, there's the people that host statics. They have a lot of privileges, like invite and kick people. They can spend company actions and update company board. But they don't have admin power on FC and they're in charge of managing their static people.
7 - Ancient Dragon: Free Company Admins. They hell with structure, organization and can buy and spend actions too. They decide some rules and are important on the modeling of the Free Company environment (there will be more info about what admins have/should and can't do soon).
8 - Wyrm: Sub-leader. It have all privileges in the FC just like the leader.
9 - Ancient Wyrm: Leader. It have all privileges of the FC and it's in charge of things.

There will be more posts about changing between groups and what admins can do soon. Stay tuned for more news!
