A rep in a state if far different than a member of the board of directors. Legally, the board of directors have ultimate responsibility for the affairs of a non for profit entity. A rep in a state may, or may not, be an employee but would not have any responsibility for the affairs of the entity.
A director of a non for profit entity should know its sources of financing and how it uses its money. A director could have potential liability if the entity has some financial problem even if the director does not have actual knowledge of the problem. A rep has no such potential liability.
Thus, I can understand why Mason would demand that a board of director member sign his posts as agent of the PPA while a state rep would not have such a requirement. Of course, Bryan needs to sign his posts as an official of the PPA because he actually represents the PPA to this group.
TE, being on the board of directors of the PPA links you to it whether or not you intend such a link. Perhaps you should examine whether you really want to serve as a director or just a state rep for Kentucky. You should seek legal advise from a lawyer in Kentucky if you have not yet done so.
