Guild Wars 2

Do someone know if the leaderboards for adventures are worldwide or for one Server only?

And did someone get bronze or even silver in Santum scramble? My best time was 2:10 and I dont know how gold should be possible.

I’d like them to work first (or know how they are supposed to work exactly)
I see 0 name in adventure leaderboards, even though my friend and guild mate have done some of them.
Must we have a rank inferior to 1000 (or anything) to appear ?

These leaderboard have no meaning if I can’t see my high score and if I can’t see the high score of all my friends. I don’t care what score other people have except the people I know…
