I'm working the layout for a school newspaper using InDesign. However, while the school's computers have CS5, installed, I have CS6 on my home computer. I can access the files from home because they are stored on the school's afp server.
What I want to do is to open the CS5 document in CS6 without converting it. I know about .IDML, but I don't want to use it as it'll result in confusion on my teacher's and fellow students' parts and we'd end up with multiple documents that might get edited independently, leading to even more confusion.
To reiterate, I don't want to export the document; I want to save it. And I only want to have one document the whole time.
