One thing I don't get is why your all posting on somthing that you don't care about, so you flame it... What's the point in posting if you have no decent answer or review?
Anyway, on topic. I can probably get some people to help you out with this. You don't want any scream or a more silent one and no Kill bitmap in the chat. Also, yes this would be usful, because the amount of times people scream "OMG HE KEILLD MEEE!!!!11!11", is extremely minimal. Dead chat added with respawn time of let's say, ten seconds. That would work perfectly fine. Just maybe adding in, if your looking at the cliet being killed, you will see the Kill Bitmap in the chat. While you aren't looking, nothing appears.
Stop flaming, and start actually helping out, or contributing...
