Hi and welcome back. Ok, so...you've opened up your "subscription folder" by double clicking on it? And you see a bunch of "bookmarks". There is a little box to the right of each one if you're in the right spot. Put a check in the ones you want to delete, you can check all that you want to delete at one time. Then scroll down to the blue box that says "selected threads" at the end of your list. Click on it, and options pop up, of of which is "delete". Put a dot in that box, then click "GO" at the bottom of that box. All the threads you checked should be gone. Post if not, we'll get you straighted out! The new board is wonderful....does take some getting used to, but lots of help is available
