I submitted to them awhile ago. They asked for full, and then we had some back-and-forth about the series I had proposed. Ultimately my submission was rejected b/c they had a similar project on their books already, but I was told I could submit another project in the future.
I found their dealings with me very courteous, and professional.
What email address did you use? I don't have my email on this device, but I can post the email address I used when I get home. But it was the one on their site, I'm sure.
