Anyway, get ready for unexpected vandal drill. All of you users that are online when the vandal vandalized the page must detect the vandalism made to the page and revert it back, and contact the Administrator.

This drills will be done UNEXPECTEDLY. If no user detected the vandalism, then you fail the test....NOT. Just make sure you can do the procedures when a vandal is abusing a page.
