@DeanRyou bring up an interesting point. I'm fairly certain that the site by default only uses the original post as the Read/Unread indicator. I understand you might read a post, then come back to it later. For now, you can manually set a read post to unread by using the Mark Post as New option. I get that you might not either remember to do this or you just click off of the post. I can bring this up in our next team meeting.
However, as a site moderator, when I reply to a post, it helps me to keep the post as read. That's how I know where I am in answering people's questions. I rely on the original poster to use the @ sign so I will get a site notification that they replied to my response.
