Taken from T Morry in another thread
I say TRASH MyThreads, add a "subscribe/unsubscribe" link, have MyThreads becoming My Subscribed Threads, and when you go to the list, your threads you subscribed to are there. The already viewed ones are in normal font, and the ones with new post/content are in bold. The top of the list is the bold, most recently posted thread, then the bottom of the bold list is a thread you havent checked in since it's recieved new posts, but least recently responded. Then the thrads you've read take the same most recent view/post order.
This is such a good idea, mythreads never works anyways
