Back in April I posted news about the World Challenge competition, hosted by BBC and Newsweek. Well, I just got an e-mail from a friend reminding me about it so I went to the competition's website, only to find out that the final round is on and that votes for one of the finalists will be accepted until tomorrow.

So I encourage you to visit World Challenge, take a look at the twelve finalists and cast your vote! There are interesting projects coming from Latin America, Africa, East Europe and Asia.

Finally, a hat tip for the BBC/ Newsweek crew for the remarkable job they have done profiling these projects through video.
