DSF] See that with Elissa "Pistons" Carrey ( pistons@dumpshock.com ). AFAIK sumissions are taken from anybody as long as it's good, related to Shadowrun, under 5,000 words or so and coming as one single fiction (not a serie of 5,000-words-long episodes). It's a plus if it ties to recent releases and plots, so of course actual freelancers have some kind of edge for that. Finally you have to account the fact she's aiming at six fiction a year, and even if she gets more real good ones, it'll stay limited by the time required for editing.
You probably have little to lose sending her something, at worst she'll just delete your mail thinking it's spam. Oh, she can also blow your self-esteem, of course.
