I've always wondered why Hot Potatoes had its eye closed by default - to show it's not quite kosher? It works perfectly well in 1.9x though. And now Feedback???
I seem to remember that the reason is (was) that the original HP not being a totally free to use software, its Moodle plugin adaptation should not be available by default (i.e. eye "open"). A moodle admin should have read the HP conditions of use and agreed to them before making HP available.
Things changed almost a year ago. See Sales of Hot Potatoes and Quandary have ended. I expect that, with this new situation, there is no reason why the HP plugin should not be available be default in Moodle (i.e. eye "open").
PS.- Helen, I hope I have not ruined your promised forthcoming HP story.
Here's a post which might be useful for Helen to refer to when she writes her new blog post
