When you click on "go to last post" - 01 on the image, it seems to take a tremendous amount of resources, and frequently times out. I figure it must use some search paradigm.
However, when you simply click on the last page - 02 on the image - (or the first page - or whatever page) it opens immediately, and it is simply a matter of quickly scrolling down to get to the same "last post." I am now doing this as my usual procedure.
Perhaps we could eliminate the button for the "last post" (or change it to "last page") and folks could just click on the "last page."
