Just above the thread list in each forum..where the page numbers are, there is a statement that says "sort by last reply" (It might say "sort by post date"). If you click it, you can choose between sorting by date of the post or last reply. If you pick "date of post", you have to go through multiple pages in order to find new posts. If you pick "sort by last reply", all threads that have new posts will be moved to the top of the forum. After you have read the threads, click "mark all before XXX read". That way any new posts that have been made since you arrived at that forum for that particular session, will show up with yellow stars. If you pick "mark all read", that will not only mark the threads you have just read as having been read, but any new posts that were made while you were reading.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
