you can just go to the list of forums and click on individual forums. A forum with new posts will have a New icon in front of it. Once you get into an individual forum, new posts are in bold.
Edit:
Dennis, I guess you're right.
'New posts' shows the threads with new messages. I initially thought it listed all new messages directly.
