Reply to myself:
It was all functioning, but I couldn't figure out how to coordinate Newsletter Admin and Header/Footer Infos. The java popup help file for that was missing, and that might have explained it. It's just a matter of creating the newsletter body in Newsletter Admin and then going to Headers/Footers and associating footers with the newsletter by title.
For me I am ready to call Newsletter Module v0.21 complete in my MS2, and thanks to using all the little fixes found in these forums I like it.
