Just as a fluke I submitted to an editor that only takes unagented subs and luckily got a response. "No thanks, I think we might have something similar." I was surprised I even got an email and I was even more surprised they didn't say you need an agent to submit.
I wonder, has anyone done this successfully? I mean, has anyone sent directly to an editor (that only accepts agent submissions) and get a good response? Perhaps even a request for the full?
