Precautions while using Facebook
What stays posted
Another precaution to take when practicing online social networking is to limit what you say or post. When you put something, whether it is written word or pictures or whatever, you will want to only post what you wont mind millions of people seeing. Online social networking is not your personal diary. Millions of people can get access to what you post. And what you post will stay online forever. You may delete it, but it has most likely gone on someone elses computer and they will have the ability to put it online again. It never comes off.
