Dear Principal,
I want to suggest an idea for this school's improvement. The idea is to add a school's newsletter run by students. This will enhance the student's creativity and presentation skills. As they create a new newsletter every month, their brain will get enriched with more and more ideas.
As I suggested before, we should make a monthly newsletter. If we do this foward-stepping decision, the students will learn more than their current brain does. That will still be an improvement. We all must help our school and community by making people more aware of how great this is. 
I want the students to do this for a key reason. If any experienced staff is applied to do this one job, the newslwtter will always be in the same style. However, if the students are creating the newsletter, they will also be aware of the school and be more able to connect with other students. While the students are doing the job, their brains will be enriched with more and more imformation.
I know that all parents want to know about what is happening at their child's school, so this will also be a great opportunity for them. Also, the students love to design and create more and more things, scince it helps them and lets them use their brain. 
Now that I suggested my suggestion, I want you to do everything in your power, scince your decision right now can help our school and community a lot. I need you to let the students design the newsletter to make your school better.
