In every resource that can be collaboratively edited (learning resources, methods, tools) we should have a checkbox "This is a minor edit" just above the "Save" and "Cancel" buttons. This checkbox should be shown only to those users who are not already authors of that resource.
For learning resources (Web pages, Presentations, Exercises, PILOT's) it should be displayed only on the second page where the metadata is displayed (About page):

We should not add the name of the user who made minor edit to the byline, but we should show the name in the history page.
