I got the impression from this new system that the rules weren't changing, and that the moderation and/or enforcement of the rules wasn't changing.
It's just that now we can/will accumulate points for our infractions, and if we accumulate enough points, we can earn ourselves some time off from BYC.
So if we've never gotten a PM from a Mod in the past asking us to change our language, tone, etc,, and they haven't had to edit or delete our comments out of posts, chances are we don't need to worry, unless we change the way we conduct ourselves.
But if we're on the Mod's PM Speed Dial, and they have to edit or delete a lot of our posts, we're probably going to start accumulating points.
