I'm working for the economic promotion of the canton of Schaffhausen. Our company (Generis AG) does this on behalf of the Canton of Schaffhausen. (http://www.economy.sh/index.php?id=10312&L=4
The one you found (Gesellschaften und Zünfte der Stadt Schaffhausen) has been a private job i did as a volunteer.
My enquiry is related to my job for the economic promotion. There we have a magazine which is published quarterly. Here
you can see the last one. As the topic of the next one is "International Community in Schaffhausen" I thought I could get to know some opinions and feelings here.
