I have been wondering the same thing! Where do the old posts go? I want to be able to go back through the pages and catch up when I haven't been on for a couple days.
at the top, thre's a tiny little link that says "all boards _> Seattle Babies" - click on Seattle Babies and you'll get to the index of the posts with a green banner at the top. Up there is a thing to click on other pages of posts.
Re: How do you view previous posts, a page at a time?
