Oh Great Rejecter,
Can you please settle this argument for us bumbling masses. Do agents and publishers not take you seriously if you submit your manuscript in Times New Roman as opposed to Courier?
So, funny story. I always used to use Courier New for just about everything - my papers, things I submitted, stuff I published on the web. I loved to write in it. Then I started reading other people's full manuscripts in Courier New and discovered how irritating on the eyes it was in comparison to Times New Roman, Garamound, or even Arial. I won't judge your manuscript by your font (unless it's in Wingdings), but seriously, Times New Roman. 12 point.
Thank you, future authors.
