The Tracker module provides a light but full-featured issue and task
tracker, a ticketing system if you will, in Moodle. It is an activity
module which can be used to operate a helpdesk, as a support and
coordination tool for Moodle administration, as a task and project
management tool within courses, as a bug tracking tool, and so forth.
It allows configuring customized issue recollection records and can cascade across the Moodle Network or to another tracker instance for multilevel helpdesk constitution.
