Normally, if you click on a thread, and read thru it, then come back later, it will take you to the last post you viewed(or posted). It depends on how you go back to the thread. If you click on the thread title, it should take you back to where you left off. If you click on the arrow button on the right side of the page, it takes you to the last post made in the thread. If there is more than one page, you can click on the page numbers under the tread title to go to page 1,2, etc.
