I just now found this thread again...
Casey, did you figure out what to do about the money? If your money in in the States that would complicate things a bit..
You can definitely have a savings account in Germany and don;t have to pay taxes as long as you're earning below a certain amount (I think it's $75,000 but can't remember for sure, could look it up though) We file US taxes every year in case we will return and have money on accounts on both sides of the ocean.
Koblenz - we live in Konstanz, often the two places are confounded, Konstanz is ALL the way south, on the Swiss border on beautiful lake Konstanz (Bodensee auf deutsch). It's very nice in the summer- lots of tourists, but nice. If you ever come this way you can sleep on my couch. Hilary, I will defend you from German police. They're busy catching old ladies with stashes of greens in their underwear trying to make it over the Swiss border anyway.
It is green and historic here too. Historic downtown because the mayor during the 2nd WW gave orders to keep the lights on during bombings so they thought Konstanz belongs to Switzerland. A lot of nice buildings got spared that way.
