You can publish your custom Words album by clicking "Make Public" in the top right corner of the album home page. It is then reviewed by Osmo staff. The approval process currently takes less than one week. If you need it reviewed fast, please let us know the exact name of the album as well as the email address used for your myOsmo account.
For reference, you can find our written instructions for the Osmo Words app here:
