Dixonary, for those who don't know, is an online version of the parlour game otherwise called Balderdash! or Fictionary. This game began in the Tapcis forum on CompuServe in 1989. It is still going strong, and is now to be found on Google Groups, where its couple of dozen formidably well-read, clever and witty players are always happy to welcome kindred spirits. (But you will have to apply to join.)
The game is primarily one of exchanged messages in Google Groups. But it also needs a support site for the rules of the game, archives of past rounds, and so forth. This site makes those available.
