In the upper left of the Forum page, where it says "Top 15 Stats", I used to be able to change it to top 20, 30, 50, whatever. That option is no longer available. Just an FYI.
I remember that option as well, and I see what James sees, but it looks like it resets to 15 again after you you go back to the main forum page. I don't see how to change it (except to change the default for everyone). I'll do some hunting for an answer.
Works for me if I click "top 15 stats" and then "view more".
You're right. It does work - it has just turned white for me. So when I click the link, it opens two apparently blank white boxes. But just now, when I rolled my cursor over the white boxes, the "view more" came up. So, no sweat.
