I use Final Draft 7 and Celtx 2.0. They're both awesome programs and I recommend then for any screenwriter

I really wanna know because for me, I do. But, that's only very recently. In the past, I just wrote from the top of my head and I think that's why I could never get anything done on time, and that was why my episodes were so very short but now that I've began planning the episode step my step, I've found that it has help me out a lot and has made me a better writer. Its something I strongly suggested and recommend when writing scripts
