"Mark All Posts Read"

Is there a button somewhere that does this already, or one that could be added in?

Y'know, where, when you're finished reading all the threads in a section that interest you, you click that button and it marks all the topics in that section as read so you can see when there's new posts better.

If that makes any sense, a button that did that would be much appreciated

There's a link for that Bottom left corner of the page.

Cheers! <3
