I attended the #Irvine Tour on 8/17 and 8/18.  I would like to access the day 1 slides: the Welcome + Overview deck, the Customization deck, and Implementation deck.  I see that they have not been updated here:

I did find two of the decks under Group Files, but after downloading, they do not open.  I wonder if it's due to the animation in the pdf's.  Not sure if anyone else having that issue.
