So I have level:member. So I was wondering how do you "level up" what are the next level? What are the requirements?

I think it just marks if you're a normal member, an admin, banned, or a retired account.

Moderator, Ex-moderator, Contributor, Banned and Admin are the only other ones I've seen.

The only other levels I'm aware of are "Moderator" and "Banned". They may be another level for "Administrator" but I'm not sure about that one.
