During the morning announcements, I can have a podcast about the school library sent to the secretary or who ever is in charge of them. He or she can broadcast the recording to the teachers and students. This can also be posted in a section of my website for others to replay, if they did not get a chance to fully hear what was said or for a review.
Below is my personal podcast channel from ipadio.com. The first few are just some examples of what types of podcasts I would like to have for the future.
