I don't want to distract the discussion with technical issues, but thisDronma wrote: The real problem is that there is no replay of the teaching that oldbob is talking about.
you can also fix partially. There is the possibility to record the teaching from the webcast while running, for example with a sound recording program like Audacity (free download, easy to use). You can then later listen to the file again and again.
Of course, in this case you should at least be online at the beginning of the teaching to start the recording.
Thank you, Xango.
But, 1) now it is too late, and 2) it is not legal, nor ethical.....
