Really? The law requires us to publish that in the "Impressum"
Anyway, hints for sending stuff back to us are summarized here:
Hi. Sorry, don't know what "Impressum" is. I took a look at the page you linked, seems quite complicated to send something back. I've literally never sent a package, so this will be my first one. I just hope I do it right
Btw, when I looked through the threads for potential help/info on what I was seeking, I didn't see the one you linked to, but notice now it was at the bottom of the page on my screen, which I thought was just the latest comments, didn't noticed it had your thread pinned. My bad.
