Due to the current gap in continued funding from the U.S. National Science Foundation
(NSF), the NSF Unidata Program Center has temporarily paused most operations.

I note that there exists both 'idv support' and an 'idv users' mailing
lists. Why the dual existence? From the archives, it appears that user
questions appear on both.
