    Transcript, please??

    • Etherealmind

      If you would like to pay the $200 -$400 per show that it costs to make a transcript, then I’d look into it. We simply don’t make enough money from sponsors to be able to afford that.

      A transcript of a podcast produced by people for free? Come on, it’s not April 1st is it?!

  • L C A Andrews
