How due dates & reminders work
If your use case requires adding records regularly, most likely a due date has been set by the admin of this applet through the cadence setting.
For example, a due date for a weekly status report can be set on Fridays at 3 pm or on Mondays at 10 am.
In this case all applet users with "Submit" permission will receive an automatic reminder from status.net to post an update. Reminder will be sent to your email 2-3 hours before the update is due.
