I can find “alt.fan.utena” in the list of newsgroups available at my Internet Service Provider. How can I subscribe to it?
Email or call your ISP and ask them politely to add AFU to their newsgroup feed. If they need the control message, it is archived at http://www.deathquaker.org/utena/AFUcontrol.txt . If you do not have access to Usenet or AFU, there are a growing number of World Wide Web-based services which will allow you to read and post to newsgroups (some will only allow you to read them). For example, a good read-only service is at Xasa (http://www.xasa.com/grupos/en/alt/fanr-fanz), and (depending on your level of patience) you can read and post at Google Groups (http://groups-beta.google.com).
