I used to use C2 a lot and a big issue was collaboration. It was incredibly difficult to work on a game at the same time with someone else or even to port over event sheets from one project to another. When I first heard of C3 way back when, they mentioned it would be easier, but after looking around the program a little I can't see any new options to help with this. Any ideas how to collaborate/port sheets in a simple manner?
