The Poetry Foundation's instructions for recording your own:
"1. Join SoundCloud and the Record-a-Poem Group.
2. Hit the round Rec (record button).
3. Check the box to approve that Flash can access your microphone.
4. Hit round Rec button again.
6. Hit the square Stop button.
7. Upload the sound.
8. Name the recording following this format: 'POEM TITLE' by 'POET' read by 'YOU'; add author tags and the word 'poem' and 'poetry.'
9. Keep in mind that we have to approve the tracks before they’re added to the group, so it may take a day before you see it."
