So, I have visited Prague (Czech Republic) and here are a few links I've found related to this journey, wonderfully organized by Pavel, member of CZilla and Mozilla Europe:

Considering the busy scheduled there, I really could not spend time sightseeing the beautiful old city. I guess I'll have to come back! (By the way, what about having our next localizers meeting in Prague? The airport has great connections, the cost of living is amazingly cheaper than Paris, London or Bruxels, and I'm sure that our fellow localizers will appreciate the bars and the architecture...)
