If you have an L++ version from March 2010, we can play on Mindless' central server. It's reachable by the first button in the networking menu. If you have a later version, I'll host myself, in which case I'll post the IP address in this thread shortly before the game.
Level names don't have to be translated to all the languages. If the German field is empty, the English title is used. The German field is a relic from the early days of development anyway. :-)
