I cannot emphasise more strongly that prospective authors need to closely read the submission guidelines here.
Granted, they have been in a state of flux, because we are tweaking things, and you may have been caught out by changes. However, please read them thoroughly each time you submit, and especially before you start writing your own, personal Necronomicon Ex Mortis. (Only joking, 2000 words maximum, please!)
Thanks for the stories and keep ’em coming!
