Yea. I would have liked to hear the content of a few of them myself.
In fact, I even contacted one speaker (Robert Shanebrook) two weeks ago but still have no response....
(I will never understand teachers who are reluctant to teach, esp. with students who really care about what teachers have to say!
I heard back from the speaker.
There does not appear to have been any record made of the talks nor their detailed contents....
