A ways back there was a mention of spoof e-bay e-mails phishing for your personal info. Usually they’re not to hard to spot, because if you roll your cursor over the link they want to take you to, you’ll see they’re NOT going to http://www.ebay.com. However, lately there have been some really clever ones that look EXACTLY like e-bay’s address, with one little twist. Instead of a slash (/) between address elements (for example, http://www.ebay.com/index/viewitem), the address has dots (.), for example, http://www.ebay.com.index.viewitem.
It’s just a good idea not to open anything you’re not expecting, of course!
