Usenet is a collection of online discussion groups that are accessible from a large number (at least tens of thousands) of Internet sites. If you are at such a site, there is a good chance that this link to the news.announce.newusers group will provide some introductory material. To access Usenet in a way that will keep of track of what parts of discussions you have already read, you would typically use a software application known as a "news reader". (Such applications are available for nearly all common types of computer systems.) It is also possible to do this via some software applications that are primarily designed for other tasks, such as browsing the web. For more information on accessing Usenet, contact whomever provides technical support or user consulting for your own computer system or Internet service provider.
