Of course you've noticed that DareYourMind has joined WeChall, welcome to the club
I have also added a country-ranking. You can find it with a button at the ranking page.
Go get your country to the top of the list, or become the best of your country!
Another addition is that when you view someone's profile, there is a graph comparing their score to your own.
Keep those suggestions coming in the forum. I can't promise we'll implement everything, but we do like to improve the site based on your comments.
