Welcome to WW, Elliot. I look forward to seeing you around the site. I hope your trial membership will fill you with the inspiration to join up full time. (No, I'm not on commission!)
I see that you have uploaded some work which is presently in your archive, but for your work to be noticed it's best to join a group. Do have a look around and see if a group will suit you. Once you've joined it will appear on your WriteWords page and you can then post your work there. There is the Short Story Writers Group, or Commercial Short Fiction. There isn't a horror group at the moment, but if you join full time you would be welcome to propose one. Or there is the Intensive Critique Group which is all-genre.
