So you can be safe
Internet Safety Tips
1) Do not post any personal information. I know this has been said before. If you put your name, where you live, and your school, that's more than enough information to track you down. Especially, where you live.
2) Never meet anyone online in real life. Relative or not. It's better to have another person standing with you just in case. The internet is a place where people can hide who they really are. Haven't you did that before?
3) Never post anyone's videos, pictures, secrets, et cetera. You wouldn't want your "friend" to do that to you, right? Besides, not only is that rude - because people could post rude comments on it - but there's a reason why that person didn't want to post it online.
