I'll let Maurile clarify what he meant but in general, encouraging others to "please stay on topic and / or drop the jabs at another poster" is always something I want us to be doing.I was under the impression that @Maurile Tremblay didn't want posters correcting other posters (board cop) when things went off the rails. I could be mistaken.
I suppose someone might try to do that in an obviously condescending or contemptible way but in general, I want us all to be thinking about staying on topic and dropping the insults.
