Liz Gorinsky: I've only read three of her novels (Radiance, Valour and Vanity, and The Snow Queen) but I loved all three of them. I'm particularly impressed by Radiance, which is a complex and difficult novel and must have required care to shepherd it to publication.
Sheila Gilbert: I haven't read any of the novels on her list, but she works with some authors I really like (cough cough Seanan McGuire)
Jim Minz (Baen): I haven't read any of the novels on his list, but it's a respectable group
Neither Vox Day nor Toni Weisskopf chose to submit supporting information. I'm very curious about whether Toni edits Lois McMaster Bujold, which IMHO would be a huge mark in her favor. Those books are beautifully polished! Unfortunately, that information isn't readily available for someone with my poor search skills.
