You can set a due date on a template by selecting Set due date from the action menu on the top right corner when viewing a template.
Then you select how many days after a new checklist is created it is over due.
In this example we have set it to 5 days. This means that if you start a new checklist today, it will be due in 5 days from the start date.
we will automatically send out email reminders to all people assigned to the checklist, when the due date is near and when a checklist is over due.
