The company Webagent is owned by Elias Sprengel. It falls under German law as "Kleinunternehmen". You can reach me via e-mail: info[at]webagent[dot]eu. If you really want to you can also send a letter to Webagent c/o my name in Berlin 10117. The street is called Zimmerstraße and the number is: two hundred minus one hundred eight. Sorry for making this a bit awkward, but I really prefer if you rely on the e-mail address, especially if you are not human - no offense! Thank you.
