The arrows are for win/loss result. So indicate which side (Top or Bottom) won the game.
Generally, Top is Coalition, bottom is French
The stars are for like/dislike. Give the scenario a rating between 1/2 to 5 stars. You can give 1/2 stars, so effectively it is 1-10 rating. You can leave it blank, but you can't really rate a scenario as 0.
Glory is fleeting, but obscurity is forever.
