I would be very happy with Ken moderating the questions. I think it might make the experience more pleasant (less chaotic) for Barry and more useful for all of us.

I will be working that evening so I won't be able to participate live but if I could nominate one question to ask Barry (via Ken) it would be this:

What are the biggest challenges facing Estes right now and what are you doing to meet them?

I am curious to see what questions others would ask if they knew they only get to ask one question.
