Bonnie,
As long as you havent changed any settings, your threads should be appearing with the newest replies first. You can check this by looking at the far right column, Last Post By - which shows the day/time the last reply was made. If you accidentally clicked on that Last Post By area, the threads will show in reverse order. The little triangle arrow there should be pointing down.
To figure out what you have read or not, be sure to check the Icon Legend near the bottom of the thread listing to see what the icons before each thread means. They let you know what you have or have not read. Also, unread threads show up in a Bold font. Read threads show with a regular font.
Let me know what you are seeing....
