The community of computers comprising a Usenet typically does not include those of end users, e.g. home personal computers. Rather, that community consists of a group of cooperating servers. End users must have access to a member of the server community to read and post. Such access is typically achieved through the news feature of their email program or web browser or through a special program that specializes in netnews. Configuring the program requires the URL of a server, and often a user ID and password.
