My German ain't that great, but good enough to get around.
Welcome to the forums. I am sure you'll settle in just fine, we're friendly, but we can be a bit tough when it comes to in depth discussions and for most folk I recommend having thick skin, people tend to say what they really think, but appreciate honesty, which we don't always get from theists. I suspect with the elections drawing nearer and nearer the Americans here will be kissing out asses, because I hear word some are thinking of moving if Romney wins and they'll need a place to stay until it all blows over.
So I think this is a good time to be a non-American new member.
Jokes aside. I'm a Brit, I used to live in Germany when I was a toddler (Munchengladback) and tend to head over to Germany for the Wacken Open Air music festival (North of Hamburg) and was there last month. I love the place - or at least the parts I've been.
I would say the rules are a good guide to discussion for around here. I hope you enjoy your stay and get something positive out of it.
