The Importance of Proofreading Your Spec

You must proofread your spec before you ask someone to read it.  A reader will tolerate a handful (no more than five) typos before they stop reading.  A typo, by the way, is when your type "anothet" instead of "another" because the r key and t key are next to each other.  But using "there" when you mean "they're" throughout the script or misusing a comma (or not using a comma at all) is not a typo; it's a grammatical error.   And readers are much less forgiving of grammatical errors.  Flawless story structure does not make up for poor English skills.  If you want to be hired as a writer, you must submit a script free of grammatical errors.
