When you submit your form, you will see an evil red error message at the top that says "Unable to send email" - do not worry, your form has been successfully submitted.

Your artists are going to come across this so you'll need to always be communicating its presence there, similar to what I'm doing with you now.
We will set up with your Facebook page and email accounts shortly.
