How can I view a thread with newest posts first?

I've tried digging through settings and searching but I can't seem to find out how to do this. Can someone help? Thanks.

I just go to the end and read  backwards

You get lost quickly here reading newest posts first.  The best way I've learned is to load up the last page and read it chronologically, then if you need to go back farther go to the previous page and start at the top again.
