grenv: 100% agree with that 12 hour Fischer game suggestion, but even having them in any colour would not prevent it being done unless you monitor every fisher game and make sure you are back on before the shortest time in one. In other words, if you have a lot of them you may as well stay here 24/7. In fact i think there should be some sort of built in safe guard, just can not think of a sensible one
I have lost track of how many of those games i have timed out of BECAUSE of that.
You go to bed thinking you have no moves for at least 12 hours (for example) only to come back hours later to find your opponent in a fisher clock game moved and you timed out.
Hence i dont sign up for any now if i can help it, which is a shame as i enjoy them.
