It's been a while since I posted anything new in this forum, so I thought perhaps a reintroduction is in order. I'm Matt, and I'm happy to moderate this occasionally traveled forum. I think most of what people ask about in here is memoir, which is clearly a popular nonfiction area. There are at least dozens of other forms of nonfiction, too, so don't be shy if you're interested in other areas.
In the past, I've created threads about book proposals. Those threads can certainly bumped back into contemporary use or we can start new ones.
Let me know if there's interest in any specific areas that haven't been discussed previously.
FWIW, I try to chime in on the memoir queries I see, but I don't always see them, so I apologize if I've missed yours.
