Is there any solution, beside Google Groups, to read Usenet groups (and post to them) from any computer? I am looking for something that is closer to a newsreader, with scores, mark-thread-as-read, ignore-thread, etc. I would like to be able to access this service from any computer, including my iPhone.
Are there web-based newsreaders that I could install on a server at home? Or some company that offers this kind of service? I does not have to be free, although it would not hurt...
Thanks.
