HI Eddie and Mario,

I don't usually get involved in semantics and I have a great respect for the technical
knowledge of both of you, but as I see it Ed is right the that Fmaj7/D = D-F-A-C-E
but that both of you are wrong about D9, which as I understand it is, D-F#-A-E
and Dm9 which is D-F-A-E.

If you regard D-F-A-C-E as a single chord, we would know it over here as Dm7,9. Maybe
it's a regional thing?
