Hey,
I recently came accross a website,
www.speakupstudios.com.
They allow you to record a podcast with an unlimited number of guest hosts from any working phone. I'm still not quite sure how it works, but I know that it's free. They allow you to post the podcasts up on their site for free as well on a profile page. Could be a nice way to save on your own servers bandwidth - you know. Plus, from what I've seen, it's very user friendly. Some of the other podcast websites can be a bit tough to navigate.
Anyone seen these guys before?
