The staff who set up and record the video presentations are great. I appreciate the friendly professionalism with which they select speakers, record the presentations and support the logistical needs of the speakers. Sometimes presentations could be better if the speakers understood that, if they give NBI enough advance notice, they can often revise the topics or subtopics to better fir their expertise. The only poor presentations I have seen were when speakers tried to cover topics about which they had no experience. One thing that would really help on the day the video is broadcast: when viewers e-mail in questions prior to the end of the program, forwarding those questions to the speakers prior to the end of the program would give us a chance to give much better answers. As it stands, we hear the questions for the first time at the end of the broadcast and are expected to respond quickly. When the questions are known in advance, I'd appreciate the chance to think about them a bit.
