In some scenarios it would be tremendously useful to have a log of which characters performed certain skills at certain locations and at a certain time.
(Example: Griefer mines a tunnel in someone's base in the middle of the night when most are offline)
(Example 2: Jerkface drops soil from his inventory via doubleclick onto someones crops to destroy them)
(Example 3: Player uses "stuck" at a certain location at a certain time)
I don't know if such a thing is possible but if someone is capable of putting it together I'd be really grateful & hopefully I am not alone in thinking such a tool would be very helpful in server administration
