Hello people, I'm new to screenwriting - having had all my writing experience in stage - so I'm of course in need of much advice about various things. One such thing is the software / programs I should be writing on. It's always been a given to me that Microsoft Word is the obvious choice, but I've recently been led to believe that if I'm to be taken seriously as a screenwriter, I need to buy screenwriting software. My confusion comes from perhaps not understanding what these programs do that Microsoft Word does not. Must I spend money for software that perhaps I don't actually need? I guess the obvious follow-up advice I need, is if screenwriting software is a must, which ones would you lovely people suggest?
