Avoid "flaming" (inflammatory or antagonistic criticism), or sending insulting, abusive or threatening remarks. A "flame war" is the back-and-forth volley of insulting e-mail and is considered a waste of network resources.

Remember that e-mail is not necessarily private. Your message can be forwarded to many people without your knowledge. In addition, most e-mail servers have programs that archive the e-mail messages that they handle.

Before sending a message, read it over, make sure it's what you want to say, and double check the recipient(s).
