I believe the `logsys_categories` table is where many of the logging features can be enabled/disabled. Don't ask me what they do or what they mean. I haven't tinkered around with them yet to fully understand it.
As far as other questions go, fire away, it serves you no good holding back. Besides, it doesn't seem very active right now and questions that need answers will engage certain types. Don't expect me to know the answers though, you're my scapegoat.
