The best place to find all my recent fiction collated into one place is my blog, at
www.homebasecomics.com/blog/It hasn't been updated recently because I've been working on my novel(s), but eventually I'll write some short stories and toss them up there. I don't have any of my older EVE fiction there, though. However, if you do a search on the official forums you can find some of my older stuff, like Water Angels and Piloting in the Nude.
They've also got a fair bit of my stuff at
http://evechronicles.com/ They've even got some neat illustrations for my stuff.
The method of submitting things for EON is drastically different now, so that post is worthless. Essentially, CCP tells Zapatero "Hey, we want a story about XXX." And then he contacts a few people on his EVE Fiction Writer List and asks if anyone wants to do it. I'm the only person who ever has so far. Mainly because you have roughly 1 week to send him an idea, then maybe two weeks to write it once CCP OKs it.
I'll get in touch with Zap and see how newer writers might go about breaking onto his list.
