We need some signage to help explain these connections for the better educating the public. I'm only suggesting some type of flow chart here. Needs to be done by a pro, maybe our guest speaker at the volunteers reception? "Neal Portnoy" If we could explain it in a picture, I think it would simplify a complex relationship. Years ago I needed one to figure out how to program 6 pieces of software to talk to each other. One of the software developers I was working with, created a simple 1 page drawing. I then had a clear picture of who could talked to who and listen, long story.
