I love authoring software. With this stuff, you can do almost anything.
Years ago on my Commodore 64 I had a program called CANDO that could make presentations. Then on the Amiga there was HELM, a clone of the iconic Mac HyperCard, which was truly awesome software.
CourseLab is similar to those ancient tools. It has all sorts of boxes where you control the course. It has internal controls, so you could do some fancy branching or personalizing. You could probably write an adventure game using CourseTools. You could build a web page with it too. Why not?
I am currently bouncing back and forth between it and eXe, another fine free tool. I am enthralled with both and still don't know which one to begin my projects with. It is clear that CourseLab has more power and therefore more potential. It seems to be well supported, too. It may take a bit more work to grasp than eXe, but it will be worth it for anyone planning a seriously deep lesson.
I have not tested its SCORM compliance, but all reports are good.
