Hi Christoph,
everything alright, thank you very much for your quick reaction!
For all others, to put things right:
My reply to the registration email seemed got flagged as spam, so Christoph did nothing wrong at all, because he didn’t recieve these emails.
I wrote him from the contact form on his website, and he replied immediately.
So everything is okay, the job is safe … thanks again at Christoph!
Yours, David
