I've been looking for the button to mark all the posts are read, but I can't find one.

Can you do it?

If so how?

There's two options - There's a "Mark all posts as read" link at the very bottom-right of the main forum listing, or when you click "View New Posts" there's a similar link that will appear at the top of the topic listing on the right.

 

They're there - honest

That they work is completely another issue

They do unless there's something I'm missing?

The on from "View new posts" doesn't seem to mark them. At least no for this session. Let's see the other one.

 

Note that this is the 1st time I've actually used either of them.

 

EDIT: Nope, neither works for me, I even closed IE and also forced refresh (CTRL + F5). And I was actually kidding when I made that previous post.

It should work, but if it doesn't, if you log out and delete your cookies and try again it will

Works well for me on Opera.
