The stream kicking practice originated when we used to stream recordings of past shows between live broadcasts. We used to do that when we first got in to Second Life and wanted to provide a constant source of audio for those stopping by Worldbridges land there. At that time, if someone wanted to grab the stream and the person who was streaming the recording wasn't around, it was necessary to 'kick' them. We stopped the automatic streaming because it was causing more confusion than it was worth - is this live or recorded? If we can figure out a way to make that clearer for visitors, we may start doing so again, but in the meantime, stream kicking will usually not be necessary unless someone forgets to turn off the stream, which does occasionally happen.

You can only do so once the skypecast has begun. When it has, right click 'join this skypecast' on the skypecast page, and paste it in to your your call form. Delete the characters before the '+' and after the last number and add to conference. You can see this done at the beginning of this screencast: http://webcastacademy.net/screencasts/skypecast/index.htm
