If you are a screenwriter and you don’t know about this yet… you’re welcome.
This software is free and it is the only full featured screenwriting app that allows you to collaborate with multiple writers using actual current collaborative software technology (ie the same kind of social technology we use online every day of our lives). It pretty much makes every other screenwriting software out there seem like it was designed in the 80s… which it basically was, and therefore hasn’t really changed since.
If you use Google docs, Dropbox, even just Twitter and have wondered when a screenwriting application was going to come around that made collaborative screenwriting as easy as Facebook messaging… wonder no more.
I have been using all the different big boy software for over a decade, and I am currently in the process of migrating everything over to this platform.
