river.fysh.org hosts an INN-powered news server. However it currently only carries a very small subset of newsgroups due to past bandwidth restrictions and lack of interest. This may be reviewed in future but anyone wanting full Usenet/Netnews access should first check with their ISP for what service they offer.
Note that important announcements about fysh.org services have in the past been made on the newsgroup fysh.announce which is only carried on news.fysh.org. These are the same announcements as you'll see, when there's a new one, upon logging into a river.fysh.org shell account. Furthermore any post made to fysh.announce will be sent out on the Fysh-Announce maillist, and likewise any post to that maillist will appear in fysh.announce and by extension upon login.
