Just because you read something on a piece of paper someone sticks on a bulletin board doesn't mean it's good information, or even,or correct for the matter. So you have to be sure that whoever posted the information knows what they're talking about, especially if you're doing research! But what if you're communication with online, you could be on dangerous ground! You should never give out any personal information to someone you don't know, not even your name! And just like you can't believe the information on every website out there, you can't rely on what stranger you "meet" on the internet tell you either. Just like you could make up thing about yourself to tell someone, someone else could do the same to you!
