Agnostos
Agnostos is a simple web-based task management system, allowing you to maintain a set of todo lists for a number of people, departments and workgroups. Features include: Tasks can be assigned to individuals, workgroups, or departments (or any combination of the above); Tasks may be assigned priorities and due dates; Tasks may be sorted by status, priority or due date; Auditing data is recorded for each task (time and date of each change of status, priority, or individual, group or department to which it is assigned); Weekly Report Generation (produces a plain text report of all work done by a particular user, workgroup or department in the previous week).
