I have been using Gcast to create and upload podcasts to my blog. Now I see that they are closing up on Feb. 1, 2010 and not taking anymore uploads. Can anyone suggest another 'free' site where I can upload from? Thanks in advance for the help.
I am using the Snowball Microphone by Blue. It is studio quality and very easy to use. Kids love to record since the sound is so awesome. You should be able to get one for around $150.
