When a moderator/admin tells you to stick to the topic?What I don't agree or even fully understand is when off-topic is OK and when off-topic is not OK ?
Off-topic is not on my check list. I doubt others are checking it.
But yes, like Myrthos said, being a moderator to give a warning to stay on topic after stepping in (because of insults, other TOS stuff, P&R, and such) is a good way to prevent having to step in again to take even stronger measures, which is unpleasant for everyone.
And then of course, in that specific thread off-topic IS on my checklist.
