test - moving visad-list to unidata.ucar.edu

We are moving visad-list@xxxxxxxxxxxxx to visad-list@xxxxxxxxxxxxxxxx
(visad@xxxxxxxxxxxxxxxx should also work). So don't think you have
been subscribed to the new list without your consent - it is the new
home of the old list.

Thanks to Unidata for providing the list's new home.

Cheers,
Bill
