They are listed as a pro market. However last year their publisher got sick. He's been in and out of the hospital. So their situation is a little bit up in the air. They were very interested in one of my manuscripts--going to send me a contract--but then communication stopped when William got sick. Basically it came down to a "we want to publish it, just not sure when we will be able to" situation.
I wish him the best of luck and a speedy recovery. I like the look of their books and their website.
