I'd like to know because it's just interesting, some admins have stepped down to some other role that they still have power in but it isn't displayed anywhere. Is their user group something special that's not been announced, or are they ninjas?

If it are ex admins they can be ninjas or torishop admins, not sure about the second one, for ex admins. But those are the 2 secret staff positions as far as I know.

Other than that it's just impossible to have power but no known staff position.
