I'm wondering what file format people are using for their manuscripts. I assume MS Word formats (doc or docx) are common but are they universal or even required? When communicating your manuscript to an agent or publisher what is the usual expectation? I could imagine other formats such as PDF or even plain text potentially being an option. I'm asking because I'm using an unusual format for my work in progess (LaTeX). Converting my manuscript to MS Word is doable, particularly since I'm still months away from completion. On the other hand I'd hate to have to do the entire conversion at the very end when I thought I was otherwise finished. Thanks!
