Hi, I am wondering if it is possible to send an automatic email to the user saying that his/her notification has been close. I am trying to find it out but I can't see how.

Clicking on 'Close', at least in version 1.3.2, will close the ticket with an internal note which won't be sent to customer. Instead, choose to compose answer (templates are on the right side of Ticket View screen), and then when you write your answer just select next state of the ticket to be closed successfull (or closed unsucessful). Hope this helps, Regards, Damir
