How do I add time to my opponent's clock? (Dasher)

The format is: moretime seconds
When playing a game type on the command bar under your main console: moretime 30   --   to add 30 seconds to your opponent's clock. 

Or on the bar under your board console: /moretime 30  --   to add 30 seconds to your opponent's clock. 
You may add up to 999 seconds of time. You can't add time to your own clock. 

You can add the 'moretime' command to your Quick commands.   For information on Quick commands CLICK HERE.
