Heeter's thread reminded me of this little quiz that I took a couple of weeks ago. Basically, it displays 10 emails and you have to decide whether they're real or fraudulent. See how you do http://survey.mailfrontier.com/survey/quiztest.html I was able to get 9/10 Don't read until you take the quiz: Spoiler I misjudged the CapitalOne message. It was legit, but I marked it as a fraud. I have a CapitalOne credit card, so I do receive these mails myself. It looked like the real thing, and I was going to select 'Legitimate' but the URL in the status bar of the message window threw me off at the last minute.
