Admin
Controls the forums and posts member information about the clan.
Captain
In charge of basicly everything. Well respected and honored. Can lead a team and commanders.
Commander
Leads a team into battle. How fun :].... but you must have a mic to communicate with the team. How lame. lol
Lieutenant Commander
50 posts requirement, before becoming a commander and take control of a team in clan wars you must have the minimum of atleast 50 posts. 50. Seriously i can get that in about 2-3 days without even being that active.
You can ask to apply for Administration. Theres no requirement. Not for trying to help the clan. And this job is exactly for that.
