A. Usenet is a collection of newsgroups. Newsgroups are online forums in which people discuss thousands of different topics. Each topic has its own newsgroup, and many topics are divided into sub-groups.
People post articles to the newsgroups, which anyone with access to the group can read.
Other people then post replies to the article. Some of that kind of news is certainly available online. There are over 45,000 groups available on our server to our users. Most of these will not interest you. Many are local groups for other regions of the world.
