If you have time, we would like you to think about questions for Aron and David beforehand, so they can prepare accordingly. We want to emphasize that the following is not mandatory, but will probably increase the value you will get out of the event.
If you haven't done so already, please go through some of the material mentioned above.
Please think about uncertainties and questions you would like to have answered. If your initial reaction is that you have none, set a three minute timer and try to come up with as many as possible.
