If you go into general options and scroll down to the bottom, you'll see several settings that say:
Report Casualties
Report Shot Difficulty
Report Damage
Report Expirience
Report Casualties is what you want to disable. It shows a line of text everytime a troop on the battlefield is KO'ed, one way or another (So-and-So was knocked unconsious by Whosenwhatsen)
Report shot difficulty has to do with ranged weapons. Everytime you hit someone with a bow, crossbow or throwing weapon, the game determines how difficult the shot was based on distance, if it was a headshot, and the speed bothof you were moving at. This is sort of a multiplier bonus that speeds the rate that you increase in ranged proficiencies. It only shows for actions you do.
Report damage shows how much damage you both take and dish out everytime you get hit/hit someone. It only shows for actions you do.
Report expirience shows how much expirience you get for killing people, completing quests, etc.
Also, Alexispao, you aren't being very useful, or helpful. It kind of defeats the point of posting in the tech support forum, which is there to help people
And as a friendly reminder, it's always a good idea to search the forum for any related topics before posting. Though since this board is relatively new I wouldn't be surprised to not find anything related for a while.
