Subject: Important message about Mac OS X 10.5

Please be advised that Spot and Leopard have not yet been
tested under Mac OS X 10.5 (Leopard).  We therefore strongly
recommend, if you are intending on submitting a proposal for
Cycle-5 and you are using a Macintosh desktop or laptop
computer, that you not upgrade your OS prior to the Cycle-5
proposal deadline.

REMINDER: Cycle-5 proposals are due by November 16 at 5:00 PM PST.
Cycle-5 will be the last cryogenic observing cycle.
