I'm going to push out the inagaural date one week until May 31st, partly to give
more time for this to get widely disseminated, but mostly because I need to write
down my various thoughts on where to go with UPM, and I don't think I'll get that
done before Wednesday.  That'll also give me time to setup a public calendar so
that people can get reminders and whatnot.
