We regret very much to inform you that the Conference has to be cancelled due to the European air traffic situation. In fact, the flights of a significant number of keynote speakers, speakers and attendees have been cancelled. We are looking forward to postpone this conference (autumn or winter 2010). 
The conference fee will be reimbursed directly on the credit card accounts for the people who did their payment online in the last 60 days. We will contact the other participants very shortly to inform them about the reimbursement procedure.
We are really sorry about this “force majeure” situation. 
Thank you for your understanding.
