If you are a student enrolled in the ACT program, it allows you to work through online training material and manage the submission of a collection of example images and associated forms, that define a piece of course work; henceforth known as a "Work Piece".
Student functionality is centred on the ability to study training material, fill out and submit forms related to your work, as well as use the camera function to capture examples of that work. It also enables a Work Piece specific chat function so that all feedback attributed to a piece of work can be contained within the Work Piece itself.
