Tasks are simply reminders to do something at a specified date/time. Tasks are assigned to Administrators, and can be linked to different Clients, Students or Tutors.
Tasks are typically created for reaching out to a specific individual concerning any number of things - for example, a Task could be an alert for an Administrator to send an email to a Client concerning different Tutor options, or to chase up a Tutor with an unfinished profile.
Tasks are found via Activity > Tasks - navigating here will bring you to a list of pending Tasks, with tabs for cycling between a list of complete or incomplete Tasks. The Filter button can be used to further filter the Task list by its assigned Administrator, role type, associated Job or by what type of Task it is.
