Fencer:

This is exactly why i asked.
Knowing that an idea may not but into life easily.

But i still might not have been able to show my point: Its a time-setting system which does not affect the game-time-limits.
But a limit, a countdown that counts backward _as soon as you accepted to move now_.
By clicking on a certain game, the time you have to think for one move starts counting.

The downtime is n ot affected, because if the server is down, noone can accept to make a move anyway...
