The Digital English Classroom

I really enjoyed this activity and thought it was extremely easy once the account was established. Students could really have fun creating their own podcasts.

How can we make this easily accessible in the classroom in light of the fact that it costs money to use Evoca (I think it said you have to pay after a certain amount of minutes)? Also, I used my headset to do the recording, but do most computers have built in microphones? Overall, I think this would be a wonderful tool.
