Return folder module
From MoodleDocs
The Return folder is a very simple contrib module developed by Teemu Sumi and Janne Mikkonen. It creates a place where users can upload multiple files for viewing by a teacher who eventually can decide to show selected files to all users. There is no grading or commenting option.
The userdir/Return folder module is compatible with Moodle 1.5.x, but not yet with Moodle 1.6.1.
