Users can mute the topic, that’s all I can think of at the moment.

You could run a Ruby/Rails command at the Rails command line to mute the topic for all existing users by updating their user preferences, but new users who sign up _after_ you run that command will not have the topic muted.

**Do note that only people with that topic in a “watched” state will get emailed for new replies** , and even then, only if their web browser has not pinged the website in the last 10 minutes. So you could target this a little more surgically to update all user preferences from “watched” or “tracked” to “normal” on this particular topic. Perhaps @techapj could advise on the exact Rails command?
