If you want to make a good killtracker, make one that tracks SILENTLY and never fills the screen with annoying and juvenile SPAM.
Sorry, as a server host I HATE killtrackers, and I have a rule that they can't be used on my servers. Other servers have the same rule. Most of the people I have banned are people who insist on using killtrackers despite server rules in the MOTD and everyone yelling at them to turn them off.
Most players above the noob level also hate killtrackers and those that use them. Noobs love killtrackers. It's not just me who hates them, you can read what others think of killtrackers here
I'm sorry you wasted your time making something that is so annoying and unneeded (and unwelcome). We need more killtrackers like we need more computer viruses.
