In today's release (v1.26.4.7), full support was implemented for the merchant outbox, including sending items to the Marketplace from it.
There are however a couple differences with LL's implementation:
- I didn't bother to implement support for Aditi (the beta grid), so the outbox can only send items from the main grid to the true (non-beta) Marketplace.
- You cannot move items for which you don't have copy permission into the outbox: this makes strictly no sense, since either you created yourself what you are selling (and you therefore have copy permission for it), or the people who helped you creating it must have given copy permission to you (else, you won't be able to put the item(s) for sale in more than a single vending machine/for sale primitive/magic box/marketplace folder).
Also, there is no special floater for the outbox. You simply use it from your inventory, with the following peculiarities when compared to "normal" folders:
- You can drag (copy-ok and transfer-ok) individual items and drop them into it, but instead of seeing the items moved when dropping them into the outbox, they are copied, each inside a separate sub-folder which gets automatically created (with the same name as the name of the item).
- You can drag a folder into it, in which case the folder and its contents are copied (instead of moved) into the outbox.
- You can "Copy" items and "Paste" them into it (right click on the "Merchant Outbox" folder and "Paste" in the context menu), which got the same effect as dragging and dropping the items into the outbox (see the fist point above).
To send the items contained in the outbox to the Marketplace, simply right-click on the "Merchant Outbox" folder and choose "Send to the Marketplace" in the context menu. Notifications will tell you when the send completes (or fails), and on completion, the corresponding sent items are removed from the outbox (and appear in your Marketplace inventory, on the website).
Note that the same limitations as the ones implemented in LL's v3.3.0 viewer apply to the outbox (total number of folders <= 20, total level of nested folders <= 4 and total number of items per folder <= 200). These limitations can be modified via debug variables, but unless you want to see the sending actions fail, I won't recommend changing these variables till LL officially states they can be changed and by what amount.
