It is possible to set reminders for the members assigned to the task (Who tab), but also for yourself only even if you are not one of the members in action on the task.
It is necessary to have planned a start and/or end date to set a reminder.
To set a reminder, open the task and go to the When tab of the task: at the bottom, go to the reminders area:
There are two kinds of reminders:
- Reminder for all members: a reminder will be sent to all members assigned to the task
- My reminders: a reminder will be sent to you, whether you are assigned to the task or not
Select a value in front of the desired type of reminder. Reminders can be triggered before the task starts, on the date (and time) of the task start, when the task is overdue, or when the task is marked as complete.
The recipients of the reminders will receive a notification in Beesbusy and by email.
Reminders are visible in your notification center 
If you have downloaded the Beesbusy smartphone app, you will also receive your reminders in push notifications.
Note: if no start or end time is set, the reminder will be triggered at midnight on the day in question.
Good to know: reminders can be set by default for all project tasks in the project settings.
