Rick;
Great show, I got it on the replay. One problem if you have to drop out of the replay and then come back you start at the begining again. It looks like they have code for a playback console that you can add to your program page over on the profile page that gives you all the buttons to skip forward and back etc when you use the replay.
The stamp collectors group the APS has been running a web radio show since 2004/2005 or so at www.wsradio.com, APS Stamp Talk, have a look at that and you might get some ideas. They have a free 877 number for the call in line.
