NoKill is a plugin that stops players from using the /kill command. It displays a message to the player that issued the command that it is not allowed. Not for all servers, but I created it on request, and I felt it should be released to the public.
Installation
How to install NoKill:
Download SimpleCompass.jar.
Copy it into your server plugins folder.
Thats it!
Incompatibilities
These plugins will not work with NoKill:
Any plugin with a command containing /kill will not work.
NoKill will activate, but it will stop that command from being run.
