Is there an SQL query I can use to list everything a Moderator has done within the board? Example, editing posts, deleting, moving, etc. I suspect one of my Mods has been deleting posts they shouldn't be, and need to know for sure!

Thanks

Much of that is not recorded in the DB. I think Rick may have added some of it to the latest version but not positive. Maybe one of the other regulars knows for sure, but certainly was not in the older versions.

Why not just use the Admin log? It will show pretty much everything a admin or moderator does. Except for standard posting.
Control Panel » Logs. Tab over to View Admin Logs.
Set your date range and select the go button
