As several people asked me already, I thought I give you the information as far as I know it.
No registrant has received written / electronic confirmation.
No credit card payment has been done up to now.
All credit card payments will be done end of June or beginning of July.

Sorry folks, that is about all I know.
I am grateful that those things are organized and I am not in the position to criticize those that do the work.
