Rocky - This is a policy ebay started awhile back, it happens when an item goes over $100 and then all a person sees is bidder 1,2,3 etc. You can see your name as the bidder when using the same computer you used to place a bid but anybody else will not see your name. The seller is the only one who will see all the names if using the same computer they did the listing from.
It was ebays attempt to stop sellers and other people from contacting the losing bidders with an offer to sell the same item direct thus cheating POOR ebay out of the fees they collect.
