Sorry, Peter. That's not what I mean.
I'll give an example, a good one I can think of is Shermatt's Florida finds.
Often Matt will make 3-4 posts at a time with say 10 photos on each post. I come back to the computer and hit the 'show unread posts since last visit' button at the top left of the screen. This takes you to a list of the threads that have new posts.
If you click on the 'last post' button, the little page with the turned corner and arrow pointing right, the one I illustrated on post 4 of this thread, it will take you to the Florida finds thread and take you to the very last post.
BUT
There are more posts that Matt has made before this last one. As I said before, he often post 3-4 times at once. So there may be another 2-3 posts that I haven't seen before the very last one the 'last post' button took me to. Therefore you have to scroll through 30 or more cars before you find the beginning of his new posts.
Another example, say you haven't logged on for a week or even a month, you come back to see what is new. You see someone's build thread has been busy, hit the last post button and it takes you to the very last post. But there are 5 pages of posts you haven't seen. Other forums when you hit the last post button, it will take you to the point where you have last logged in, so at the beginning of the new 5 pages you have not read, not at the very end of the thread.
The way it is now means you have to read or skim through backwards for 5 pages until you find your last spot.
