Each time a bid is received, the auction panels for the items will automatically change to display the name (in gray) of the latest bidder, right above the red bid buttons. You can also view the top 10 bidders for an individual auction by going to the item's details page and clicking the Open Bid Log link. As bids come in, the list automatically updates.
Note that bids can be coming in rapidly and you may not see your name appear every time you bid. If you just placed a bid and you see someone else's name appear, it probably means that person placed a bid a fraction of a second after you did. If you do not see your name on the Bid Log, you could be experiencing technical difficulties and you may wish to contact one of our Customer Care representatives for assistance.
