Hi reflected,
Sadly there's no real way to do this atm. We have a mission log and regularly monitor chat etc, but without tracks of problems or problematic people it's impossible to see everything that goes on. I think many people are still stuck in the IL2'46's way of the last bullets = a kill. Which you very well know, isn't the case anymore (THANKFULLY!). We'll throw up some more messages about shoulder shooting / team killing, but I think once all the people recognize you only get credit for the damage or % of damage you cause to an enemy, stuff like this will hopefully weed itself out.
And we're here for the long haul
S!
