I would also set us a My Ebay screen on your computer. I would start to be nervous that, OK, I lost that auction. How many did somebody win using my account???

By setting up a My Ebay screen you will be able to see what auctions you have won, what you have lost, and what you have current. If someone did get your password and is bidding using your identity you should be able to find out. Changing your password is an excellent recommendation. Do that as fast as possible and notify eBay. Not just to stop someone from bidding on your behalf but because, as I have seen and heard happeing with AOL, you don't want some ID theif to change your password and lock you out of your own account.

I don't recall how I set up the MY eBay screen but I think there will be a link toward the top of the eBay page. I don't know if it will just come up or if you will need to put in your password or anything.

I have the My eBay screen set up and have had that linked as a home page on my IE browser. That way every time I signed on I would see right away all my ebay activity. It is a good way to keep track of how your bids are going and if there is any unusual activity taking place.
