How do I share work with my overseas colleagues, we are all working on different topics?

I would recommend using UPK’s multi-user environment, It allows multiple users to work on the same module simultaneously where as in single user environment you’d have to do a lot of exporting and importing of odarc files. Even though it’s possible to do with out Multi-user you’ll spend most of your time copying/pasting and fixing broken links manually. Multi-user would be a MAJOR time and hassle saver.
