We're still on for the December 15th classic shut down date
Stocking up on WUs to send during our science
database merge next week. If all goes well, 
there won't be a "real" outage - just a 
"behind the scenes" outage.
A backlog of 2M results to send
should last a few days.

And once we're done, mass e-mail time!
We're still on for the 
December 15th classic shut down date
even though the e-mail won't be going 
out until the 18th of this month (or later). 
There will be postings on the web site
and the classic clients
will all be popping up windows
warning of the impending shutdown
before the mass e-mail starts going out.
