There is no reason why other coordination groups need to jump thru the hoops (what you called "provisions in the bylaws") of the ORRC to become coordinating bodies. Instead they can do exactly the same as the ORRC did and have their 'constituents' recognize the group they desire. If it was good enough for the ORRC, it should be good enough for other groups.
Except, John, when the ORRC first organized there was no other recognized group. In this case, there is a corporation that has been doing the job for 20+ years. That founders put a clause in there to allow another 'organization' to demonstrate their ability, and demonstrate the support of the constituents, at which time the existing group would hand over the responsibility. That seems very reasonable to me. Let's take this off list, I doubt anyone else cares about who was a member and when. 73
