Just a little suggestion from your loveable Moldplayer....
I have not been a admin for very long, but i have noticed a bit of a problem with the Tk icon for the opposite team. (pardon me not making sense) As you all know when someone teamkills on your team, it comes up as a vivid dark red, much different then the lighter scarlet colour of a friendly being killed by a enemy. However, when a enemy teamkills another enemy it comes up as the same bright green as a normal enemy kill.
On bigger servers it can be a bit confusing when you have to process all the green from enemy's being killed as well as well as the chat etc. My suggestion is that the shade of the enemy tk be changed to say, a turquoise, or blue colour (like the allies in SP) it would make finding tkers easier.
Dont know if this is possible though....
