How to be safe online

Internet is a fantastic place where you can share your ideas pictures and keep in contact with firends. But unfortunatley the internet is also a dangerous place and to be safe you have to follow some simple rules, the rules of the Netiquette:
1) Be clear online: be clear in sending email and text messages, spare abbriviation and sarcasm, and don't use capital letters unless you are really shouting.
2) Respect other people's privacy: if you are sending an email to more than one person write their adresses in the BCC( blind carbon copy) so that other people can't view who else you sent the email to. 
3)Be sensitive: don't tag pictures of other people if you didn't ask or their permission. You also shouldn't discuss other peoples buissnesses on a wall anybody can view.
4) Be educated: do not swear over the internet even if it's just for joke, and try to make peoples lives easier by placing a subject on the emails.
So baisically treat the others like you would like to be treated.
