Netiquette

Netiquette, a portmanteau of "network etiquette", is a set of social conventions that facilitate interaction over networks, ranging from Usenet and mailing lists to blogs and forums. These rules were described in IETF RFC 1855.[1] However, like many Internet phenomena, the concept and its application remain in a state of flux, and vary from community to community. The points most strongly emphasized about USENET netiquette often include using simple electronic signatures, and avoiding multiposting, cross-posting, thread hijacking, and other techniques used to minimize the effort required to read a post or a thread. Netiquette guidelines posted by IBM for employees utilizing Second Life in an official capacity, however, focus on basic professionalism, maintaining a tenable work environment, and protecting IBM's intellectual property.[2] Similarly, some Usenet guidelines call for use of unabbreviated English[3][4] while users of online chat protocols like IRC and instant messaging protocols like SMS often encourage trends in the opposite direction.

As will the cyber bullying I would worry more about what students are sending and receiving online more in their homes than at school. Since many districts have limited email, chat rooms for students on school computers.
