SpaceWesterns.com is a soon-to-be launched online magazine for "space westerns, science fiction westerns, and western science fiction." Watch a few episodes of Firefly and you'll get an idea of the kind of universe they're planning on exploring.
The site is revving up for its formal debut, and is the process of soliciting submissions. Editor (and long-time friend) N.E. Lilly reports:
"We’re currently collecting stories, artwork, and other content for an April 1st launch. Join our announcement list to get an e-mail reminder for when we launch, and, if you’re interested in providing fiction in any from of media then visit the submission guidelines page for information on current rates and guidelines."
