I did. I taught them a little how how phishing works. I also showed them what happens to their information when they fill out a form for entering a contest - how mailing lists are generated, which is why they get so much junk mail. I used a database program, made a form, had them fill it out, and then I generated lists of students who met certain criteria. I covered much more than I put in the article, but for brevity's sake, I left some things out. Thanks for your response!
