Hi,

On Friday my wife went into the hospital with serious pain and mobility issues. She is now back but has been asked to avoid stairs.  Unfortunately this means I have to take on some responsibilities that I was unable to hand off properly to my sons.

At this point I have to assume I will be unable to travel for the next couple weeks.  If you are interested in having me present remotely, I can do that.

I am sincerely sorry, and also disappointed as I was very much looking forward to visiting Jinan and presenting in person.
