GUADEC is the annual conference of the GNOME community, held in Europe since 2000. GUADEC is the world’s largest gathering of users and developers who are involved with the free desktop and mobile user interfaces. GUADEC 2013 will be held in Brno, Czech Republic, a city which has played host to several other successful GNOME-related hackfests in the past. GUADEC is expected to draw hundreds of attendees who will discuss and direct the future of the GNOME project. Developers, artists, translators, users, and representatives from government, education, and businesses, and anyone else who shares an interest are welcome to attend. And we need you to give a talk!
