Announcing ScrabbleMOO, a server running at 188.8.131.52, port 7777 (nextsrv.cas.muohio.edu 7777). The server software is version 1.7.0 of the LambdaMOO server code.
To reach it, you can use "telnet 184.108.40.206 7777", and sign on. You will have a unique name and password on the server, and directions are provided in the opening screen on how to accomplish signing on. The first time, you will need to type "create YourName? YourPassword?", and each time thereafter, "connect YourName? YourPassword?".
There are currently 5 Scrabble boards set up, with global individual high score and game-cumulative high score lists. Games can be saved, and restored at a later time. There are complete command instructions at each board (via the command "instructions"); usage is simple and intuitive. There are commands to undo turns, exchange tiles, and pass, and there are a variety of options available to change the way the board and rack are displayed.
We do not yet have a dictionary for challenges installed on-line, and that is coming very soon. I am seriously contemplating using the OSPD.shar wordlist that Ross Beresford listed in a recent Usenet article. It seems to have the full wordlist from the 1st edition of the OSPD, plus longer words from some other source. I have personal wordlists updating the OSPD to the 2nd edition, for words up to 4 letters long, and will have the longer words in the near future.
Usage of a certain dictionary for challenges is not enforced, and really can't be. Many of the regular players there have their personal copy of the OSPD. It's all informal, and for fun. Players agree what dictionary to use on a game-by-game basis, though the OSPD is encouraged. There are even commands to enable kibitzing, if watching rather than playing is what you're into.
