Overall, it was a good event, a good venue, good lineup of the speakers and also exhibitors. There are two issues that I saw was I did not see many retailers who are essentially users of delivery services. I didn't see many of them attending and also generally the number of visitors was lower than what I expected several of the sessions. Specifically the talks there, we did not have many people in the audience, which was a little bit surprising. I don't know if it was due to the timing of the event or the way that the tracks were split or it was just a weaker promotion prior to the event. But those are the two areas that I would suggest that you guys work further on for future events.
