Would it be at all possible on each players preview page to show the TIME difference between lets say London (UK British Summer Time) and Beruit (Lebanon, being 2 hours behind) and / or Sydney (Australia, being 9 hours difference). It would then allow all opponents to see if a player was likely to be in bed or about to return home from work, so a move might be pending.
At the moment with no time indication shown, you can sit waiting for hours and then just after you log off, the next player logs on.
Just a thought, if its technically to difficult then its to difficult.
