dirkriehle.com is a privately owned and operated website. The owner, not surprisingly, is Dirk Riehle. You can reach me by email using firstname.lastname@example.org or by phone at +49 157 8153 4150.
The postal address is Juvenellstr. 3, 90408 Nuremberg, Germany. However, I apparently live in a slum and postal mail is not guaranteed to arrive. I recommend you use registered mail or simply send email.
