CLEARAKILLS

Usage:
This will remove all the global klines or akills from your server. This command does not affect any other servers.
Examples:
/clearakills
It tends to be a good idea to remove akills after a while. The person it was set to ban may have either reformed or stopped trying to log in. Any other users who may have matched the ban coincidentally will not be able to log in and chat until the akill is removed.
