Last post read?

I may be missing something right in front of me, but I've never seen anything for being able to go to the "last post read" in a thread.  There is just the green arrow to the right of the thread list for the very last post.

Am I missing it somewhere embarrassingly obvious?  It's a pretty standard feature on forums and I'm surprised we don't have one here.  Particularly given how fast this forum moves.

*bump* Nobody? Nothing? I can't believe I'm the only one who is either just not seeing this feature or would like this feature if it doesn't actually exist.
