Newsgroups offer an open forum for discussion. Newsgroups work something like e-mail but are more akin to global electronic bulletin boards.
Articles sent to the newsgroup are viewable by anyone subscribed to the newsgroup.
The level of discussion also varies, from intellectual to inane. The name of the newsgroup should be an indication of the topic, if not the level, of discussion. Google . is a good place to find other newsgroups. For instance, Netscape Navigator 1.1N and all later versions come with a newsreader so that you can link directly to the newsgroups listed below by clicking on them. Ask the computer support group at your school or the service group at your online service provider for the name of their news server.
