Hi Clemens,
I really can't believe that a respected topaz level member like yourself would discriminate other users by asking them not to reply to your question. Surely you are being VERY disrespectful to other members.
If you have a direct question to Dr Horst Keller (or someone "like" him), I'm sure you can figure out his email address. (tip: it's first_name dot last_name at company dot com)
Regards,
