I'm one of the editors for The Doctor Who Project, a long running fan
fiction series found here: http://www.thedoctorwhoproject.com/
We're looking for some new writers to contribute to a 'season' of
stories for 2013.
You'll see the submissions tab in the top right corner of the front
page - TDWP has its own version of the Doctor and two companion set up
at the moment.
If you're interested at all and want to know more, or have a story
idea you think might work, please e-mail at tdwp (at)
thedoctorwhoproject.com or PM me here and I'll forward it to the other
editors. We'll consider anything, anytime and just about anywhere.
