On the main page there is a form with a name entry field and a "Hello" button. When you click on the button, if the name first appears, display "Hello, <Name + Surname>" or "Hello, <email>" (of your choice). name".

There should also be a link on the main page, when you click on it you need to show a list of everyone you have already greeted.
