Hi MaryKatherine. I just go down to the bottom of the page and click on Archive. There, if I've already looked at a thread, it is pink and my unread ones are blue. It is broken down into the different topics, but I usually just look at Main, Pictures, and Introduce Yourself. If it's a thread that I want to follow like the Scrap Quilts one, I simply go to Thread Tools at the top of the page and subscribe to that one. Works for me. I no longer even look at the Daily Digest. It just doesn't do what I want it to do at all. Hope this helps you. I love Quilting Board, but the Daily Digest took a nose dive in this new format.
