How do I post a story with audio?

Choose the "audio" option from the "create content" list you get when you hit the "publish!" menu above.

You'll be taken to the audio upload page. Click on the "Browse" button to select the audio on your computer that you want to upload. You can enter the body of your story in the box marked "Body." When you're ready, hit "submit."

If you leave the default title of your audio, "%title by %artist", you will then be prompted to provide the title and artist for the track.
