"The membership fee is extremely reasonable, considering that it gives you a year's unlimited playing time... plus access to lectures, interviews and coverage of major events." — Sarah Hurst, Chess on the Web
Example : "moretime 30" -- adds 30 seconds to your opponent's clock
The moretime command is used to give your opponent extra time in case of lag.
"moretime -30" will NOT subtract time. :-) You may add up to 999 seconds of
time.
