What is Moodle Reset Function?

Please answer this if you can, and then retag it. Thanks

What does the Reset function in the Administration menu do?

And

From canMary Parke:

“The reset function allows you to remove all user data from a course and reset it’s start date each term – to “refresh it” one might say (content stays and makes it beready disabledfor ornew removed?users). IsIn there1.6.x ait reasonallowed you to keepchoose it?which data to delete from discussion forums. So, it doesn’t surprise me that it defaulted in 1.8 to resetting roles of the instructor. What I would do is reset the course and then manually reset the instructor’s role."

Note: use with knowledge. One of ourthe Alpha test instructors clicked it and her role was switched from teacher to student. That seems dangerous.

Any details on why it’s considered useful would be helpful.
