Who's on Helmley, who's asking to join, and a record of everything admins do here.
Suspend stops someone signing in and keeps their data; Restore undoes it. You act only on people below your role. Someone who has asked to delete their account can't be changed until it goes or they cancel.
Explore groups courses under these, in this order. Each course's creator picks one on its Publish card. Hiding one lists its courses under Other until it's shown again. Only owners see this card.
Who sees this: only the site's admins (admins, super admins and owners). Every decision about a person (invite, approve, decline, withdraw, role, suspend, restore, and who's let into a course) is recorded with who did it and when, and nobody can change that record; a person's email leaves it once they no longer have an account (the privacy page explains). Learners' private data is seen only by owners and super admins.
