HOW CAN WE INCREASE AUDIENCE PARTICIPATION IN WEBINARS, both numerically and during the event?

After the above webinar, in which only one of the 5 people present really participated actively, I wrote to Kora about how webinar participatioin might be increased. As one of the non-verbalisers, I realized that when Kora had asked a question my mind had gone blank and I supposed this may have happened to others too. Were we suffering from Performane Anxiety? In my case I thought my silence could have been explained by the fact that  this was my first Metahealth webinar for over 4 years; during this time I had been involved in other things and had not been able to keep up with the conferences or the other activities offered by the Association. However, I also felt that for me it was more a question of SAFETY.  I wonder if anybody agrees. Kora was very interested in understanding better how to increase motivation, so we thought of inviting you all to express your own ideas. Here are a few questions to consider:

Why do you think so few people attend the webinars and what could be done to increase their numbers?                                                               
What could be done to motivate more attendees to participate actively in them? 
Do people feel uncomfortable about being asked questions on the spot, especially when there are so few people present?                                      
Would it help if the webinar speaker were to publish the main questions they would be asking prior to the event, so that people could prepare themselves beforehand and be sure they had something to say?                                                                                                                             
Would people actually prefer to watch passively, without being asked questions at all? 
Do we need a made-to-measure  EFT course in public speaking and would somebody like to offer one?

Any thoughts on this question would be gratefully received!                                                                                                                                       
Many thanks,
