Staerfeldt, Hans Henrik (1990). "New mud comming up.. [sic]". alt.mud. We have started to program a mud, that we hope will be finished some time in the end of the summer. This mud will be better (we hope) than other muds as we have learned from their mistakes.
Hammer, Sebastian (1991). "New Mud". rec.games.mud. We consider playing in groups to be one of the more important (entertaining, that is) aspects of mudding, and hence the game includes various features, especially designed to make group-adventuring more fun and rewarding: Four different classes of players, with various abilities; a system which allows members of a group to share the score made at a kill; and lots of other stuff.
