The Distributor is a sub-type of the Sloodle module, and it works with the Sloodle Distributor tool in-world. A single Distributor module in Moodle stores the list of inventory of a Sloodle Distributor in Second Life, and controls access to it. You can add as many as you like to your course, but there should only be one Distributor object in-world for each Distributor module in your Moodle course.
