Das Krakenhaus Publishing is still on the lookout for short stories under 12k words in the genres of scientific romanticism (such as H. G. Wells and Jules Verne) and Steampunk. I believe they pay only a small stipend, but if you are looking to get some writing credits, it’s a great way to start. You can find the information on submissions here.
DKP is a small, independent press that accepted my short story, Winter, which will be coming out this spring in a book of short stories called It’s the End of the World as We Know it.
