New to the Habitable Zone, "scienceman"?
Welcome ~
I don't know the Dutch equivalent -- is "wilkum" correct?
In any case, my greeting is somewhat less than enthusiastic, due to the manner of your first appearance. Believe it or not, we seek to maintain a sense of decorum here. In plain English, that means:
No matter how strongly you may feel about someone because of what they say, criticize their message, not the messenger.
Got it? Good.
