The standard rules of UseNet are that there are no rules or better yet the rules change dependent on the people who post there. Despite that fact there is a sort of code or etiquette of how one should post to a Newsgroup. Certain "rules" are more powerful or take precedence over others, so following or breaking certain ones might be more important dependent upon the newsgroup.
1. The society of UseNet creates these rules based on community behaviors.
2. Follow the proper netiquette defined by the newsgroup's participants usually found in that newsgroups FAQ.
3. Post related topics to the appropriate newsgroup using the newsgroups title, as the topic controller. Some newsgroups are text only while others are binaries only.
4. Don't abuse or misuse the UseNet system, or violate the societies behaviors.
