Thank you Ugo

Because of a job change, Ugo Taddei will be much less
active in the VisAD community (although he may still listen
to the mailing list).

This is just to thank him for such an excellent tutorial
(which we will now serve from SSEC) and for all the help
he has given to the mailing list. And to wish him every
success in his new work.

Cheers,
Bill
