A protected page is a page that normal users cannot edit or move. Users can still rate and add comments to any page.
Very few pages on this wiki are protected - most articles may be freely edited, rated, categorised or commented by any logged in user. The exceptions are those pages that are linked-to from the static website; the names of these files are protected to ensure that a page is not moved so links to key entry points are not broken. The pages themselves may still be edited freely however.
