Hi Rod,

I'm glad you're enjoying Adapt.  To answer your questions:

1. It's not yet possible to import a course -- unfortunately with versioning, it's slightly more difficult to import than export.  This is a feature in the product roadmap though and some development has already started.
2. Multi-user support is also due in an upcoming release.
3. Do you mean that you'd have a 'master' copy of courses that you'd like users to take and modify, while leaving the original intact?
4. The company I work for (Learning Pool) specialise in facilitating this.  Please don't hesitate to get in touch.

Thanks,

Brian
