Wikipedia doesn't mention anything about EDNS versions, so I'm not sure what to make of it. "It's a policy-induced disaster. ... eurocrats .... the euro is standing between them and recovery ... Europe is stuck with a fixed exchange system that doesn't let them print, spend, or devalue their way out of a crisis"
There's no source or data for any of these claims, so you can skip the article. IMHO, it's just an anti-euro rant. Why wouldn't Europe be able to print money like the USA does? Article doesn't say.
Maybe a heat map of all sections based on completion percentage? And maybe a way to jump to the first or a random unsolved puzzle once you've opened a section?
