Hi Herk,
The Speaker's Agreement was really an agreement that your likeness and (I'm pretty sure) materials could be used without compensation. But I don't seem to remember anything about giving away rights to your presentation slides. So in theory you should be able to post your slides on your web site.
But I don't have the agreement in front of me, so I can't be sure. Plus I'm not a lawyer!
I would like to post my slides as well, if I can do it legally and they don't get posted on the Sun site.
Hopefully Chris can clarify this when he returns from his much-needed break!
