'New posts' in a thread have something indicating that they're new.
For example: You see a thread in "gold". You open it. Then you scroll down. You see all the new posts marked with and indicator that they're new. Then you exit the thread. The thread is no longer in "gold". You re enter the same thread, none of the posts are marked as new because you had already viewed them all before.
Normally in a thread the bottom most post shows the newest post. In our forum, we have to look a the dates. As cool as reading is, could we cater better to the lazy and impatient?
