I think there are more rules in a knife fight than what we have on the ATAG Server. Actually, just two come to mind:
1) No swearing, obscenities, or abusing another player in chat or Teamspeak (there are kids, after all, either playing or in viewing/listening distance of some home computers),
and
2) No deliberate shooting of team mates. (Yeah, friendly fire incidents sometimes occur which is not the issue at all -- we're talking of some cretins who would join the other 'side' and go "renegade")
What IS allowed is "vulching" (er, airfield suppression
), shoulder shooting, shooting aircraft with wheels down, shooting down badly-damaged a/c in distress, etc etc.
That's it!
