Now, if you had been introduced by an Austrian friend you met in Germany instead, you would just be welcomed... no questions asked!

Just kidding!
But seriously, I find this forum to be very helpful. Especially, I try to use the search function to find previous insight on what I need to know. Most of the common questions have been discussed extensively in the past.
Of course, when in doubt, ask! You may be referred to a previous / existing thread, but you'll get a helpful answer.
