|Resuming adjourned games|
When you or one of your opponents in an unfinished game log onto the server when the other is there, you will each be immediately informed that your opponent is online. To resume an unfinished game you need only type the command resume in the console. This will issue a challenge to all of your opponents who are online and available.
To challenge a specific individual you can also type match <handle>. This will automatically offer to resume the adjourned game against that player. You cannot begin a new game with that player until your adjourned game is completed.
Also, the server automatically issues the "resume" command for you any time you post a seek.
