Second Life Viewer-Managed Marketplace
This viewer allows Merchants to manage inventory associated with Marketplace Listings from within the viewer. In addition to making management of Marketplace Listings easier, sale of items that Merchants do not have the right to copy will now be supported with Viewer-Managed Marketplace.
Until this feature reaches the default Release viewer, users must be running this viewer on ADITI (ACME D, E, or F) for this feature to be used. See the wiki page for more information on how to try out this project viewer: http://wiki.secondlife.com/wiki/Linden_Lab_Official:Viewer-Managed_Marketplace_FAQ
