I know that this forum is for Garritan instruments, but would it be possible for those arranging jazz/big band pieces to offer vocal tips and techniques?

The reason I ask, is because I know David Maddux through his wonderful work with First Call. He is a great arranger and I'm sure there are others here who could offer some excellent tips and perhaps lessons for the recording/arranging of vocals in these styles.

If this is not a good idea, does anyone know of a forum where this could be discussed?
