I added this function because I needed it. Suppose you read a post and would like to respond; only it is complex and you don’t have time at that moment. You can now mark the thread unread so that it will remain in your New Posts list. While viewing the thread, simply go to the menu above the posts, click Thread Tools, and click Mark Unread.

Note: The New Posts function can only contain posts ten or fewer days old. Otherwise, new users would have 200,000 new posts.
