There has been an enormous amount of progress over the last two years or so on the scientific and technical case for a neutrino factory based on a muon storage ring. These are being comprehensively reviewed at the Monterey NuFACT00 workshop, 22-26 May. The seminar will describe the current status of the machine design and ideas about detectors, as well as highlight the broad range of physics that could be addressed by such a facility.
