podcasting

I really had a difficult time with my podcast for some reason:/  I tried to do it on my mac at first, but for one reason I could never get it to read it as an MP3 file.  I finally downloaded the programs on my dell laptop and was successful.  Anyone else trying to do these assignments on a mac? I am practicing  trying to set up a blog now, and hopefully it won't be as difficult for me.  This class is a challenge for me for sure.
