Let me try to make this as clear as possible (because people on other forums seem to get confused as to the actual question). At the end of each sentence, after the end-punctuation, do professional readers prefer two spaces before the next sentence, or is one space acceptable. I'm not talking about lines between paragraphs, only spaces between sentences. It seems a hotly debated topic online, but I haven't seen any opinions from actual script readers. 3. 2. 1. Go!
