Beware of misinterpretation. Mail With electronic mail, you are in potential contact with millions of individuals. A couple of lines are OK, but signatures longer than say five lines are definite breaches of netiquette. Since one news article from you could be seen by millions of others, it's very important to follow the proper rules of netiquette. In news, there are thousands of different news groups, each with its own focus.
Some groups are only regional in nature.
A brief description may be displayed beside each group in the top level of the 'tin' newsreader. A more certain way is to read the newsgroup for a month or more before posting any articles yourself. This list contains the questions that come up most often. Asking a question in the newsgroup for which the answer is contained in the FAQ is a breach of netiquette. If you decide that an article that you post should go to more than one newsgroup, you can cross-post it.
