Chat log doesnt show commands used, just chat.. hence the name "chat log"
Check out the Action log table in your database
Code:
USE PS_Gamelog
SELECT * FROM ActionLog
Can add a WHERE clause at the end of that aswell to specify which GM you wanna check, or for which command you wanna check.
Code:
WHERE CharName = BadGM
There is also a query in Ariez release of guides that brings up GM commands that have been used, called Naughty GM i think.
But then again, why have a GM that you dont trust and that you have to check up on to make sure they are being good little boys and girls?
