IT WOULD BE GOOD TO HAVE AN OPTION SO THAT "MAIL ALERT" NOTIFICATION CAN BE MADE ABOUT A TASK, BUT WITHOUT GIVING ACCESS TO THE SHEET. THE CURRENT DISADVANTAGE THAT I HAVE IS THAT I HAVE LIMITED THE DOMAIN OF MY COMPANY, THEN I AM NOT HERE TO SHARE THE SHEETS WITH EXTERNAL USERS. BUT WHAT I WOULD LIKE TO DO IS NOT TO SHARE THE SHEET, BUT TO NOTIFY THE EXTERNAL USER ABOUT A TASK, REQUEST THAT HAS BEEN ENTERED.
