>>I do not believe presenters who desire to offer up that which they've learned, for the purposes of helping other people, for the base purposes of teaching and sharing that which they themselves have been blessed to obtain, should ever impose hindrances which ultimately prevent others from learning from their findings. And the producers of such events should never impose such hindrances either.

Rick, you're looking the gift horse in the mouth. If people are willing to prepare useful material and present it, the response is "thank you." If you can't make it to the conference for whatever reason then you might try "I can't make it to the conference but I'd love the material." Converting it to a moral right that the genocidal presenter apparently is trying to deny you on purpose, seems designed to offend. Not sure that's the intent, but we have experienced something similar before when certain provocateurs used to love to claim that objections were to their message rather than their presentation- but it doesn't lead anywhere and local experience was that proponents of that ilk turned out to be wrong about just about everything they said.
