In the past I have been able to see who is bidding on my wares. Last night I had a couple of bids on an item and could see who it was. Now I have several bidders and the identity of them has just gone to bidder1,2,3 etc and even when I try to click on them, I still cannot see who it is.
There's a new function whereby the seller can allow bidders to remain private...you must have it inadvertently clicked. (maybe it's an opt-out rather than an opt-in as yet another buyer protection thingummy?)
