How can I share a set?

There are multiple ways to accomplish this. You can email the set list, export it to Dropbox or even Beam it.

To email: In OnSong > Select set you want to share > Tap Share Menu > Email > Select OnSong Archive > Send.

To export: In OnSong > Select set you want to share > Tap Share Menu > Export > OnSong Archive > Export.

For both email and exporting, when you get to the formatting screen, tap the wrench icon and select "As a single file". This will allow you to import the setlist as a whole instead of individually.

To beam: Check out this video tutorial: https://www.youtube.com/watch?v=cDq37zhkdUk

Note that, by default, beamed songs do not permanently stay in someones library unless the person beaming them gives permission to do so. They will need to go into OnSong > Utilities (gear icon) > Settings > Menu Settings > Sharing > Expire Shared Sets > Never and Loan Shared Songs > Off > Done. Then when they beam their content it will be added to your library.
