From the web page of Mittelpunkt:
"LARP-MittelPunkt will take place for the fifth time. From january 15th to 17th 2010 it offers its participants the possibility to exchange with other larpers and to get new ideas about larp. The LARP-MittelPunkt is modelled on the Knudepunkt/Knutepunkt/Knutpunkt/Solmukohta (nodal point), an annual international larp conference that alternates between the nordic countries of Denmark, Sweden, Norway, and Finland since 1997."
