New reply

EDIT:
You mean where it adds an <hr> line when you post a new reply? This is done when the last post and the new reply timestamps are lower than X value and are by the same user. MyBB automatically appends the post to the old post, instead of creating a whole new second post.

i think we are talking about the same thing here

There is no notification to new posts that anything has changed

All users (except yourself) should get a notification of a "new post" when the last post on a thread is edited. There is a specific plugin installed that's sole purpose is to do just that.

An hour later

It shouldnt be that long. Let me check the settings if i can remember what that settings name was
