That’s the latest warning from CBS News.

When you create a profile on a popular Website like "MySpace" or "Facebook", you’re not just sharing the intimate details of your life with your family and friends. Whether you post off-color jokes, photos of underage kids drinking beer, or inappropriate comments about your classmates, millions of people can see them. Including parents, teachers, prospective employers, even the police and the FBI.

• Experts say that schools across the country are using Internet postings to discipline and expel students. College admissions offices and scholarship committees are using online profiles to narrow down their choices – a rude awakening for kids who thought they were just having fun. And racy photos are hurting people’s job searches. The Web has become an easy source of information for job recruiters – and your career can be sabotaged with just one click of a mouse.
  
  
• And even if you take the pictures down later, the damage is already done. You may not realize it, but networking sites are archived – which means that everything you post is saved forever.In fact, once your profile has been up on the Web for 3 days, it has already been archived somewhere. What’s more, the website owns the rights to your pictures once you post them – which means the company can do whatever they want with them. And that could be a real problem if you get famous, or decide to go into politics.
  

Bottom line: Unless you’re willing to attach your "MySpace" profile to your résumé or college application, or see your photos and comments on the front page of your local newspaper, don’t post it on the Internet.
