Care to explain the Member Levels

[Ninjafossils]

Under everyone's names there is a ranking that is given to the member. These include green, junior, full, hero, etc. Are these based on how many posts you've made, or how long you've been on the forum. And do the "Metal" rankings symbolize charter status?
