It's not the threads I'm missing, it's the single postings. Take for instance the "Hey!! Let's get some action going! What are we reading" this thread is huge with a lot of postings all the time. If I'm away for a week or two coming back I don't know where to start because I'm coming to the last post and haven't got a clue on which page I left off.
That being said a function where you could bookmark on which page you're at in the thread would be awesome.
