Alt.games.nomic (a.g.n) is is newsgroup dedicated to the discussion of the GameOfNomic and NomicLikeGames. In particular, it is proposed as a discussion area for interaction between existing EmailNomic games
Alt.games.nomic is suffering from poor propagation. Please encourage your newsadmin to carry it.
If you can't get this group, Nomic discussion also takes place in rec.games.abstract or alt.fan.hofstadter, and most of the a.g.n readers lurk in these groups too.
