How odd? New posts should show up in bright blue on the title page(s); ones you've looked at will be a pale blue unless there's a subsequent post. Then to bright blue again. On the title page (all current postings in bright blue) it will show the tread name and number of pages that may follow. If you click on the tread name it should take you to post one/page one unless you click on one of the page numbers. There it will take you to that page.when looking at a post , if you come back later to view it again. how do you get to the last viewed post that you saw? I can get to the very last and first?
