[London] Registration ceph days london

Dear ceph day organizers, Me and 3 colleagues of The University of Groningen (Netherlands) are planning to visit the London Ceph days. In all my haste planning the travels i forgot to sign myself up. Unfortunately the signups are now closed, is there a way i could still sign up or get notified when someone cancelled? Thank you for your time and consideration. I look forward to hearing from you. Kind regards, Steven Woudstra Team HPC Rijksuniversiteit Groningen
