Just an idea:

I thought it would be quite good to have the country flag on the ranking page, to see how the different nations are getting on at a glance.

I like that idea.. that would be interesting

Hm..i dont know..only the minority of Users selected their Country...for me i dont care which country is "best" :/

That's true. Many users not registered their country, so it wouldn't really make sense to do this.....even though I would really like to see this idea in action hehe.

I agree with Chaosdreamer that can be same as Formula 1 ranking, users ranking and countrys ranking...

I suggest that the top five users for each country made the countries ranking.
However the users must be register their country.

We Vietnamese have only 3 users, and I'm the only one who's active
I think we shouldn't have country ranking, but including the country flags in the ranking page is a good idea (I don't have to click on the username to know where he comes from )

BTW the flags are there now

yeah nice erik. i also noticed the new buttons. maybe they just miss some padding to the right.
and how about an option next to the challenges link that shows only your unsolved challanges. that would make the page more readable and reduce traffic.

Hmmm now, I think it would be a good idea to change the clock for each user according to which area/timezone they come from. That would really be nice as well.
