Age group doesn't really matter.
We have very little amount of people we are currently rank 3 which means we have bank slots and a custom free company logo.
We don't have voice chat, but me and the top leaders do use Skype to communicate back and forth.
I'm currently working on my crafting classes and maybe a few dungeons here and there.
I'm a mostly causal gamer cause I don't have much time to do hard core dungeon runs or raiding.
