Hi Vic
If you look to the left side of your screen, above and also below any board or any topic you have a few numbers, these numbers represent the number of pages the topic has, for example, if a topic has 200 pages, about 3000 posts, you see these numbers [1]23..... 199,200, you just need to click the number 200 and you are on the last page, where you have the last posts, you don't need to browse all the pages, just look to the numbers and you will see how many pages of posts has any topic, just click the last number and you have the newest posts, let me know if you have doubts.
