I've previously jumped between two separate machines while doing level editing. Passing files via email was fine but I've had to add a 3rd place to work. So I'm thinking of putting some time into having a better work flow. Especially one that can handle version histories.
I typically use source repositories for plain text type projects and use dropbox for art assets. I feel like levels and their accompanying script files are an inbetween concept. What does everyone recommend?
Secondly, when this is all set up I think it would make level numbering much easier if the repository is open to anyone who wants to do editing. Not that we would mess with eachothers maps, but if they all had one home then we could set asside a set of numbers for a specific project.
