Hi,
what i want to suggest is: change the colour of the black bar, the one that you see above posts, only on posts from the thread's creator.
I think it would be useful to recognize immediately thread's creator while you are scrolling the chat. If he is posting some updates or replying to someone... If you are searching for a post from the thread maker, you can switch faster the pages because you can see immediately his posts.
This option could be activated/deactivated while you are making the thread. Depends if it is useful or not in a certain type of thread.
