Isaac Asimov once wrote "People often think I have the answers, when sometimes I don't even have the questions".
I actually froze my Moodle site the week before a major summative assessment for the human pathology graduate course. It caused major distress in most students, who could not use the many excellent learning resources available there.
You don't really know how useful your Moodle site actually is until someone (like me) freezes it
I have updated the Moodle Docs page for Installing plugins.
Please feel free to add/remove/change it as you think it should be.
