Computers. Love them or hate them, it is impossible to escape from them in the modern age. They are so much a part of our everyday lives—from instant messaging to e-mails. With many people preferring to use e-mail rather than traditional regular mail, it has become very important to be aware of how we express ourselves when using e-mail. The requirement of etiquette（网络礼仪）is obviously needed.
Grammar and spelling
Firstly, if you are dealing with a formal e-mail, pay close attention to grammar and spelling. Don’t forget to run your spell-check (program) at the end of the document, but don’t treat it as the final word. Carefully re-read it yourself, as sometimes even spell and grammar checking programs come up with some strange explanations. Remember, your first e-mail to a potential employer or college could be your last — you won’t want to spoil your first impression by making basic errors.
E-mail addresses
Also, for official e-mails, carefully consider your existing e-mail address. A funny e-mail address (such as pinkfluffycutiepie@…com) may be fine for using with your friends, but what impression do you think this address might give to an employer or college admissions officer? Consider using one address for personal e-mails and a different one for formal use.
Upper case（大写字母）
Take care also NOT TO TYPE UNNECESSARILY IN UPPER CASE, as this is the e-mail version of shouting.
Personal information
You should beware too about giving away too much personal information over the Internet. It may feel much more comfortable to “talk” using instant messages as there are no uncomfortable silences or awkward moments, but never forget that—unless the person you are speaking to is a friend or family member—you really know nothing about them, so be careful. Further to this, NEVER agree to meet a stranger that you have spoken to online, as it can be extremely dangerous.
My final message though is—have fun! The Internet is exciting, useful and informative. But, as with so many things that we believe we can’t live without, it is a much better servant than a master.
