If you go the the BMW CCA site (bmwcca.org) and click on the link the the O'Fest site, you'll find an O'Fest specific message board (that looks a lot like the Org - same free software). The latest posts there (and I assume THEY know) indicate that the CCA will post the winners on their site once they have all been notified by telephone. But it may take them a day or two to call everyone.
In other words, sit tight and, if you don't get a phone call by tomorrow, you probably didn't win.
