Rodney was something of a polymath, with expertise in all of the Augustan subject areas, plus publication, editing, and organizational skills. The title he held varied widely over his term, with Director, Executive Director, Coordinator, and Princeps Societas prominent among them. All meant the same thing: Rodney was in charge of all.
His legal relationship with the Society also varied, at times being a volunteer, a direct employee, and a contractor, the last often through The Hartwell Company, of which he was the sole proprietor, and generally the entire staff. These various approaches were efforts to address the evolving legal situation, his financial needs, copyright and investment limitations, and other factors. They did not represent any substantial change in what he did or how he did it, the copyright of various publications being the only visible indicator.(Copyrights held by Rodney Hartwell or The Hartwell Company have all been transferred to the Society.)
He also organized and operated other groups, including the [[Octavian Society]], [[Heraldry Society of the USA]], [[International Chivalric Institute]], [[Association of Knights Bachelor]] (Yugoslavian), The St. John Volunteer Corps, and held high office in several orders of chivalry, multiple chivalric memberships and honors, and kept close company with the late King Peter II of Yugoslavia and the organizations he sponsored.
