Netiquette refers to etiquette guidelines for online communication and interactions. The four basic rules of netiquette are to help new users, research before asking questions, remember that emotions may be harder to convey online, and that people represent themselves, not organizations. Specific guidelines are provided for sending messages appropriately, such as being brief, staying on topic, and avoiding flaming. Guidelines are also given for replying, confidentiality, and respecting copyrights.
