I'm Powerek38 and here at Wikimania 2011 I serve as one of the reviewers in the Scholarships Committee. In other words, if you apply for a scholarship, I'll be one of the seven people who will read and score your application.
I live in Warsaw, Poland and I serve as sysop at the Polish Wikipedia and Wikimedia Commons. This is my second year at the Scholarships Committee. Good luck to all applicants!
