Hi Masino,
This below is a great MOD:-

BUT can you please please modify this so that it send an email to the customer i.e. creater of the ticket when closed by staff, so basically the other way round, the same way an email is sent on an update. I have tried playing with the code but no luck, this would really be appreciated by so many people.:)
Kind Regards
Surjan
