I have always been a Slash fan, even before I heard the term. In the 1990s, I discovered the existence of Slash, and that other people wrote it. Next, I discovered that Slash was being published on the internet, so I got myself some internet access and began to read it. Eventually, I began to write it, too.
First I wrote a long, still unfinished fantasy epic about Jim Ellison and Blair Sandburg, in The Sentinel fandom. I moved on to write many stories in Starsky and Hutch fandom, under the name Jen Hall. Now I write in Smallville fandom, using my Greenlady alias.
I'm not actually a fan of Smallville. I used to be a Superman fan, but Smallville changed that. Now I'm a fan of Smallville's Lex Luthor, and all my stories feature him as the hero.
Most of my fan fiction is m/m Slash, but a few stories feature f/f Slash and a couple of my stories are Gen.
