Are you sure you know how to avoid scam Web sites that look like real businesses? Do you know a family member or friend who you think might get taken in by one of these "phishing" sites?
Anti-Phishing Phil is an online game provided for free to teach people of all ages how to know when it is safe to click on a URL. It was created by a university student using Flash. It looks like a child's game, but has plenty of good information, and it drills you on the the lessons in an entertaining way.
