A Polish website I've never heard of before called Elkander has launched a Witcher contest. The prizes consist of a leather mousepad, a poster and a press pack case which are sponsored by CD Projekt. The questions require knowledge of probably all 7 Witcher books by Andrzej Sapkowski, which means that only Poles, Russians and Czechs can win it anyway, since those are the only languages in which all books have already been published. Beware, as the site is full of spelling and grammar errors, even in Polish!
