Thanks for the response. I use submission grinder, and I know there is Duotrope. But still--how are you finding all those sci-fi mags to submit to?! After about ten to twelve rejections, I'm struggling to find places.
Only 10-12? Not to worry, one day, you too will be Jedi.
I haven't used Grinder's search function, but Duotrope's is excellent, I can find in an instant, open venues interested in the genre I want, and the payment bracket I am interested in.
