I see now it is more than just a leaderboard. It rolls advertisements for various GC/NBC sponsors. I see no way to dispose of the distraction. Bad design, unless one is raking in the $$$ from the sponsors.
That wouldn't be us.
If this is a portent of things to come...it is bad news, friends.
EDIT: It's more than just a one-off skills challenge. It's the standard WGT playing window embedded within the GC website. All features are active. I was able to create a stroke round at Oakmont.
Fascinating.
