Despite well documented advantages, attempts to go truly "paperless" seldom succeed. This is principally because computer-based paperless systems typically do not support all of the affordances of paper, nor the work process that have evolved with paper-based systems. We suggest that attention to users' work environments, activities and practices are critical to the success of paperless systems. This paper describes the development and effective utilization of a software tool for the paperless marking of student assignments which does not require users to compromise on established best practice. It includes a significant advance in the task management support.
