If I login to the Coffeecup website but do not go to the forums, then some time later I go to the forums everything is marked as read ie. There is no "new posts" button/icon.
Also, I said this before but... just say a thread has 60 posts and I have only viewed 30 of them the "new post" button should link to post #31 rather than #60 just like the way the old website worked. It has been a real pain the last year or two to have to scroll through the posts to see where you left off
When you know you don't have the time to look at all the posts open the page with new posts in two tabs. When your reading posts use one tab to read. If you stop and come back and you have been signed out sign back in than go to that second tab of unread posts and right click the post link you want to read and select open in new tab. This will allow you to at least not have to hunt for them.
It's easy to overlook something you're not looking for.
