I've Switched Back to Ulysses

Ulysses isn't designed to be worked by on a team, but sometimes you do want a team to be able to work on something. You just make it very clear who's working on what when and don't both of you work on it at the same time. I've developed a system with my assistant where if she is working on the script, it's because I have physically moved it into a different folder within the Dropbox hierarchy. And then when she's done, it gets moved into a folder that indicates to me that her work on it has been completed.
