I am trying to figure out how to add someone to my course. This is a course that I have created for myself - it is a development copy of a course, not one that I would offer to real students. I have added people before, but when I try now, the + People button is there, but I can't click on it -- it is grayed out.
Some facts that MAY be pertinent:
I am using google chrome. My institution has switched to the new user interface just two days ago. There is no end date set for the course.
