I'm not sure what you mean. Are you regularly marking the forum read? If so, there's already a "Show New Only" link if you're seeing all the messages in a thread - and you're free to edit your profile to show ONLY new messages.
If you gaze deeply into the names of the people online, you may notice that if they are in the process of starting a new thread or leaving a new reply, their name will appear red (or black) on white background.
