Linden Lab have blogged that the new Viewer-Managed Marketplace is available on Aditi, better known as The Beta Grid. The blog post informs us that :
The new Viewer-Managed Marketplace (VMM), now available* on Aditi, allows you to easily manage your inventory on the Second Life Marketplace using the Second Life Viewer. Items no longer need to be loaded into the Merchant Outbox or a Magic Box, and are instead sold directly from your inventory.
VMM will allow all Merchants to get off of Magic Boxes in addition to supporting modification of listing inventory directly from the Viewer. While Merchants will still need to go to the Marketplace web site in order to edit listings, they will be able to create listings and list or unlist them from the Viewer.
The blog post is accompanied by a Wiki article and a Knowledgebase Article which both have extra information and instructions on how to use the coming new feature. The Viewer-Managed Marketplace (AKA VMM) addresses some outstanding issues from Direct Delivery. The first is a biggie, VMM allows you to list no copy items. Currently, Direct Delivery does not support no copy items and merchants selling no copy items have had to continue to use magic boxes.
Another issue is that there have been intermittent issues with the Merchant Outbox and VMM addresses those issues too because once this is fully rolled out there will be no need to move items to the Marketplace because they will be being sold directly from your inventory. At this point can I just add, I remain unconvinced that this will end well, but we’ll see!
