Bah, I hate this question. It roughly translates to "Have you already registered at StudiVZ?" If you're a student in Germany, you'll hear it at least twenty times a year. That's why a fellow student and I invented Nicht StudiVZ, just so we don't have to answer that annoying question over and over again. It's a sort of a not really seriously meant countermovement against StudiVZ. I have no idea when we'll finally put up a useless page for Nicht StudiVZ, but this will be the logo, featuring this dreaded question and a bold "No" as an answer.
For those not familiar with what StudiVZ is: It's a fake Facebook for German students.
