I can QUIET SET subscribers who want the discussions (as well as newsletter and ads) to OTHER, NEWS, and ADV. For subscribers that want only the newsletter, I can QUIET SET them to NEWS and ADV only. This last group would then NOT receive any "discussions" (i.e., messages with No topic, which fall into the OTHER topic area).
