Huh... interesting... thanks..
You will be able to sort it by the last comment. Kinda the same as color change. Look below, I replied on your post when you were 10 days clean. It came to the front page.
My only complaint is that after you read a post the title of the post no longer changes to a different color... I like to be able to tell if I missed reading a post or what new posts have been made since I last logged in..
