Literate Parakeet mentioned this online mag to me and told me they say they never get enough historical or western shorts (up to 3000 words). So, below is their website and they do say that. Their pay rate is questionable - token to professional payment based on their assessment. There is a thread in bewares and background checks on them - nothing bad, just mention of similarity in rejection letters and questions about the pay. So far I haven't seen anything here on AW about an acceptance. So, without further ado, here's the link to submission guidelines.
