I had a terrific time at the SharePoint Saturday event in Irving, TX this weekend. The developer track consistently had about 20 attendees in the room, which is way more than I've seen at SPS events in the past. In addition, there was a Q&A room, and attendees had Eric and me going for another full hour.
My presentation was taken directly from the O365 TPM group (thanks Jeremy!) and can be found on Microsoft Virtual Academy, with the slides and code on GitHub.
Also, I want to thank the organizers (Eric, Eric, Rich, Corey, Jen, Miguel, Kyle and others I have likely missed) and sponsors (Amazon Web Services, Slalom, Planet Technologies, K2, Metalogix, RBA) for making the event a smashing success!
