posted by BRFTo me, it appears as though if you are not logged in, when you click on a thread, it takes you to the first page.
I just did it on this very thread, while logged in, and it took me to a blank page (I'm not entirely sure, but I THINK this happens when a last post was made on a page and you're getting the next page that has no posts yet). It hit back on my browser, and did the same thing again.
I tried the "last post" button from my phone (not logged in), and it took me to the first page of a thread.
edit: so my post is indeed the first one on a new page.
