This might be a bit silly, but should you double space your novel when sending it out?
yes.
Standard manuscript format:
1 inch margins all around (top, bottom, left and right)
12 point font (times new roman or courier - I like TNR, but either is fine)
Double spaced
Either a cover page or on the first page:
your name
contact info
word count
Title
genre
Then, for all the rest of the pages, add a header to all the rest of the pages that is: Your Last name/Title/page number in the upper right hand corner of the page.
Start each new chapter about a 1/4 of the way down the page.
