When voicing your views in a forum, you must be as courteous as you you would be when speaking to someone in person. Insults and personal attacks will not be tolerated. You may voici your disagreement with an opinion, an idea or an event, but always remain respectful. Great minds do not always think alike. And isn't that what discussion groups are all about?
Netiquette is a series of rules of conduct governing surfer behaviour on the Internet. Before participating in a discussion group, it is important to be aware of netiquette. If not, you could face expulsion from the group!
