I am not sure about what you are asking. (I use Standard forum for general use.) Let's assume that you create a forum, and make the first initial post. Then students reply to your original post, and to other students' posts. Any reply in this forum will be emailed to all students.
But are you suggesting that you might want to have an automated way to make a reply, such as "Good work" to every student's post, mean that if you have 50 students, that your reply is added to every student's individual post?
Well, you might need to tell us (or me) more.
