Nightmare Magazine reopens to submissions on September 16, 2012. I love their home page, btw: http://www.nightmare-magazine.com/
All types of horror or dark fantasy are welcome; if in doubt, go ahead and submit it and let our editors decide. No subject should be considered off-limits, and we encourage writers to take chances with their fiction and push the envelope.
We believe that the horror genre’s diversity is its greatest strength, and we wish that viewpoint to be reflected in our story content and our submission queues; we welcome submissions from writers of every race, religion, nationality, gender, and sexual orientation.
They’re looking for horror and dark fantasy stories between 1500-7500 words (preferring fiction shorter than 5000 words), and pay professional rates at 5c/word.
