I would like to share this link with you, but first of all, you may know Stephen Spiritcaller, Ravenwood Radio Co-Host. Here is his topic about "House Rules" link: http://spiritcallings.com/
I like that rule, cause I feel like it is yelling, or anger or whatever you feel like it is. But in PVP you may can when you are "cheering" for friends, team or other. Do not yelling at game. This is Friendly family game, please respect this game or other games.
