Thanks to CPL Poker Podcast for the heads-up. As of February 1, 2010, Gcast which allowed podcasters to record voice messages, mix in your favorite music, and share it for free will no longer be available.
From Gcast web site "Gcast.com is no longer accepting new signups, and will not be accepting new uploads as of February 1, 2010."
Just wanted to alert the community.
