Discussion groups enable people around the world to discuss topics of shared interest.
You can find news groups on topics from algebra to Frank Zappa . If you have an interest in any topic at all, there is most likely a discussion group for it. A discussion group allows people to bring up topics, questions and issues to others in the group. Others in the group can then respond with suggestions either by posting responses or sending e-mail to you privately. Most news groups are open in nature so the quality and mood of the postings can vary anywhere from helpful and friendly to ludicrously hostile.
