I will add the suggestions to our discussion list. Here is my answer to the questions regarding participation:
The dates of the Fireside Chats are not announced here but on a small internal board within the video conference server we use. Access to the conference server is through an individual account which I create when a new participant wants to join. Since all potential participants have access to the board this is where everybody looks for the upcoming dates but the next Fireside Chat dates are no secret, they are always on a Sunday at 2pm EST and the next 2 scheduled dates are Nov 15 and Dec 6
To participate the main requirement is to be familiar with Tom's material and terminology. As far as hardware you should have a webcam, a (USB) headset and a computer with a reasonably fast internet connection. The only required software is a browser - Google Chrome works best with the used conference software. To apply for participation you can write a short email to email@example.com
I will then get in contact with you and set up an account on the conference server.
