I've been working on a novel for the past seven months, and actually finished writing it, but I'm in the editing process now and the only thing I'm not sure about is one thing. I know you're supposed to double-space at the end of every sentence, but I'm not sure about after dialogue where the sentence ends in a sentence-ending punctuation. Here's a random example: "I have nothing anymore." He walks away. Would you double-space between the quotation mark and "He"? This has been bugging me for a while now. EDIT: Oh, and I'm also curious as to whether or not I should bother to underline movie, book or TV show titles. I know I can't italicize them, but I'm not sure if underlining is just for word emphasis or if it should be used for media titles as well.
