thanks, amici for your advices!
@ Buncha: didnt know that one. will keep that in mind.
@ ronnie: do you remember which one was wrong? i actually checked them all by hand, but then, sometimes it's getting late and, well you know
@ linkster: actually the story with the german isp's is a little diffuse at the moment. some laws are changing (thats at least what my lawyer said) but i will consider what you said.
your last point is what makes me more of headache. but we are here to learn, arent we?
again thanks for your friendly help.
