On the Evolution Forum, there's a section for writers to post stories that are open to other members to continue. I had an idea for a story that would basically be about many different guys telling how they transformed into huge muscle guys. I wrote the first chapter, making my intent obvious -- I thought -- and posted it on the site. Pretty soon people started adding to it, but no one picked up on my intended formula -- which was that each chapter would be told by one of the guys in the support group at their regular meeting. The only thing the subsequent authors preserved was the basic catalyst for muscle growth. After a while the story of Cal come to me and I returned to the concept for one additional chapter. I don't feel comfortable posting other people's work without their permission, so I am not running the other chapters here. Checkout the Evolution Forum in my Links section to find the rest of the related chapters by other authors.
