MyBB Community Forums

Since I moved from phpBB I and my users are missing an icon or something in every post where you can see if this post is new or old.
So if you see that a topic contains new posts, you also can see which of them are new.

I searched allready on this forum but I couldn't find a topic with an answer.

Is it just a setting which can make this possible or do I have to use (or create ) a modification?

I visit several vBulletin boards that have those icons, and they can be pretty useful. MyBB doesn't currently have such a feature, but I think it's a good suggestion.
