-- Turn off wiki
Go to Server Setting -> Account Registration select Disable Registration. This means only admin accounts can create new users. By default there is only one admin account. Wikis and groups are only created by users. By default there is only one group named Public. It has the wiki pages for the Privacy Policy, Term and Conditions, etc. If you don't want to use the wiki system for anything else, then don't create any more groups or pages.
Best,
Chris
