Due to some unexpected minor administrative difficulties, we regret to announce that the registration and hotel booking web services are not yet available. These were expected to open before end of November, but will open in December. We are doing our best for launching these services as soon as possible. Meanwhile, for those who would like to register urgently (for example to spend 2016 credits and cannot wait a couple of weeks), we may find a temporary way around. In such case, please contact us at email@example.com.
