I heard back from Vadim once he had the tracking number. (I still need to update the spreadsheet; I'm too lazy to search back through the thread for the link.)I replied to Vadim's request for payment and address last week; since then I've heard nothing. I even resent the details from a second email address yesterday (just in case the first went to spam) with a delivery receipt - nada.
If you don't hear back from Vadim in the next day or so, I suppose you can contact Sergey?
