I first came across Edulang's daily news-based English lesson service English Addicts back in May 2009 and gave it a very positive review. At the time, full membership cost a whopping 120 euros (though some lessons were available for free). Things rarely stay still in the digital world, however, and since December 2011, Edulang have been offering an annual subscription for just one euro. To be more exact, you decide how much you want to pay (so you could still pay 120 euros—or more—if you wished). Half the money goes to charity, which seems like a good way to persuade people to pay more than the strict minimum.
I still think English Addicts (see demo video here) is a great way of improving listening and reading skills, and there are now over 1500 lessons available in the archives. That should keep all you learners busy for a while.
Other Edulang applications available on a 'pay what you want' basis include the TOEFL Test Simulator and its TOEIC counterpart (which I reviewed yesterday).
