 The purpose of this website is to write a letter to your future self and send to yourself to your email. When you go in the website the screen shows you a place where your email goes. You type your email and then put the subject of your letter. Then you type your letter to your future self, saying what ever you want to say to your future self. Then you choose a date you want your letter to arrive, It can be a year or more from now. Finally when your are done writing your letter you click send to future and wait for your letter to arrive. In this website you can also read  letters other people write(you can choose if your letter is private or public). If you sign up for this website it saves your letters and you can visit anytime you want to. 
I wrote a letter to myself explaining how I am right now and how I think I will be in the future. But once I send my letter it was gone to the future and I wont be able to see it until a year from now. 
I think some ways other students could use this website could be to compare and contrast each other how they are today and how they are in the future. Maybe comparing and contrasting their grades to see if they have improved or gotten worst. They can also do it with hobbies, or secrets.
