I don't think it shows up as new since you edited a current post.
That is what I have always assumed until a couple days ago when I seen a post from ... I think Jimmy (or you
) that was edited and it looked like a 'new' post indicator was by the thread and I had already read it once, but it showed as new again.
Maybe it was just me or a flub.
I don't find or read new post by the "read new post" option, I just look at the main threads, so not sure if there is a difference there or not.
Or again, it was just me.
