I have a question! A friend of mine and I have just completed a song that we think may be quite appropriate and timely for publication in the New Era magazine. Is there a site where you can submit music for potential publication in any of the Church magazines? We have just submitted it to the Church’s music department. Please let us know if there is someway to submit it directly to Church Magazines. Thank you!
You can submit it at https://www.churchofjesuschrist.org/topics/service/create/submission?lang=eng
