Hey, good luck.
I frequent a few fan sites that offer writers a chance to share their works, ask fans about plot points and whatnot. Like a insider sounding board.
They are forum communities with many members being published writers and filmmakers.

One I feel is worthy of note is
http://aliensoup.com/forums/creative-writing.144/
Its primarily a speculative fiction fan site but there are plenty of authors that frequent.
Kevin, the site owner, has no problem with members that participate posting links to their creative works.

Then you have sites like PsuedoPod
http://pseudopod.org/
You can submit your work to be read online by voice actors on a podcast.
Not sure about the qualifications but if you look at the site you might find them.
Plus, it lets you hear short fiction stories by little name authors.

Then there is Fantastic Fiction
http://www.fantasticfiction.com/new-authors/?genre=sfh
Again, not sure about the submission qualifications but you might want to check that out too.

Booksie has a Horror section.

You gotta set up an account with them first but you can publish like lulu.
