Personally, I prefer having my subscriptions active without the constant email notifications. That way, when I log in, I can just head straight to my user control panel to see everything at once—any threads I've replied to with new posts, plus updates from the subforums I follow, like Help or Moderator sections.
The poll creator can't actually test their own setup within a test thread. If they want to see how it works, they'll need to start a new one. I'll be closing or deleting these kinds of threads once they start piling up, but I'll let these first two slide.
Your change is still just a minor "aesthetic" tweak, so that’s fine. If you had asked whether you could change your username from "Terry Wilson87" to "Macarena," they wouldn't have allowed it. 😁
