Do you salute your "other half" when he or she trounces you in a pillow fight?  Not meaning to offend, but I'll salute when I feel like it and won't when I don't.  I never prefer to in a game, I did enough saluting in real life.  Besides, whether you win and I lose or vice versa, ultimately I couldn't care less.... I'm still gonna log off and forget everything that happened before the next time I log on.  That said, about the only time I DO salute is because it's a quick, abbreviated mass acknowledgement to "way to go's".
