I would like to suggest an optional timer that you could set for each vote chess game you are participating in that would send you a reminder message after a certain amount of time (2 hours, 10 hours, 1 day, etc).  This way you would get a reminder that you have not voted yet regardless of whether or not anyone else makes any comments (which is currently the only way you will get a notification about that game after you have viewed it once).

i like the idea :D
