maus.computer.software.udo – the news group about UDO.
If your Internet Service Provider doesn't offer a news server, you can register at News.CIS.DFN.DE (a news server free of charge for private usage).
Since Google has made the old DeJa-News archive available again, you can read the news group also at Google Groups.
Because the group is imported from the MausNet, you can of course also read it directly there.
