woops...of course I meant that I exited the church. Here in germany we have to pay something called "church tax" unless you formerly adress that you exit the church. You have to fill out a form, have to go to the town hall, have a little talk with some guy about it and then you are finally good to go.
Yep, it's automatically collected by the state from your paycheck and given to the church that's on your file.
If you want them not to do that, you have to go to the registry office and have them update your file to "Konfessionslos" which often comes with fee.
The information that you've left is also given to the pastor in your region for some reason who will try to convince you to come back...
