My name is Fredrik Johansson, and I come from Sweden. I started the Doom Wiki (in its now-obsolete incarnation on Wikia).
The best way to contact me is to send an email to fredrik.johansson@gmail.com
This is my Doom Wiki user page; Wacky was kind enough to also create an article about me. I am also a Wikipedia user and a Doomworld Forums regular. I have a personal website at http://fredrikj.net
