Sending a Game Replay

[BK VII]

Hey,

I was just curious how I can send a replay of a game to a friend.

Also, does anyone know if you get more points for a win if your opponent has less characters left on the board/less wit spaces? Ex: If all I need to do is snipe their base for the win, but I choose to take their wit(s) and kill any last character I can before doing so, do I gain more points than if I were to ended it by just sniping the base?

Thanks!
