I've been writing fanfiction since I was 13 and didn't like the way an episode of Macgyver ended. My stories weren't really that good - very immature for a 13 year old, but I wrote a really good one when I was 19 based on Quantum Leap and a boyfriend I had at the time. Still my favorite.
So imagine my suprise when I found out that other people wrote fanfiction. And other authors actually posted it for all to see! So I finally wrote one for publication. It's harder than I thought, but fun to get out there.
Always, thanks to all those who post their wonderful works. You are great!
