Each period's board is frozen when it closes, so a result cannot change afterwards. These are the winners of the daily, weekly and monthly boards — and of the year, once one has been frozen.
No result has been frozen yet. The first winner appears once a day's board has been finalised — draw some mashups to put something on it.
Points are the board's own total for the period — a counted draw's score, summed over the days in it. A winner is written once and cannot be edited; a deleted account's rows go with it. About this site.
