The first was how to get to the materials and the replay. This link will get you to the SDN page for the presentation and recording.
I was also asked if it was possible to download the recorded presentation to listen to it off line. Unfortunately, the download capability is not available. you have to be connected to SDN to view and listen to the recording.
Next, for those of you in the states and in particular those in the Philadelphia area, next week March 14th and 15th there will be a class targeted to the new functionality in the external facing portal scenario as well as other consideration about using the NetWeaver portal for external access. Use this link to register. The class is called RAFP20: Implementing an External Facing Portal
Lastly I wanted to make sure you had the links to other documentation:
