I can not believe it ,Maddog and Myself are in the same place/conference/room with in Idlelo 3. It is a great pleasure and honor.
His presentation was superb today, although that i have been through Open Source and FOSS since 8 years or even more,Maddog thought me something super today (difference between Copyright and License).
You may "Copyright" your presetation but that does not prevent me from licensing under any open source content license scheme.
Copyright protects you from people that may change what you say, but does not contradict with licensing it under GPL,GNU or any other.
Maddog and such people are great resources and knowledge that making change in today's world
