Obviously, the subject, and message field are a required field to fill out to complete the message. Without a subject, there would be no text in the message subject line.

Dont think you completely understood my issue. Why can a user not send a message (text in the message field) without completing the subject (text in the subject field). Why do you state “Obviously, the subject, and message field are a required field to fill out to complete the message”.
When for example sending an email you can choose to send a message without completing the subject line…
Are you able to send a message with the subject line of a blank space?
If so, you could try removing the subject field in the message template and adding a hidden field for the subject with the value of ` `.
BP requires this, because otherwise it would get complicated, both from a code and from a usability standpoint. While you can send an email without a subject, it’s not considered best practice.
The code won’t allow you to send a message without a subject, so I would go with r-a-y’s suggestion.
