**IMPORTANT NOTE:** Think twice before restricting write access to a web or a topic, because an open system where everybody can contribute is the essence of the [[WikiCulture]]. Experience shows that unrestricted write access works very well because:
-- There is enough peer pressure to post only conform content.
+- There is enough peer pressure to post only appropriate content.
- Content does not get lost because topics are under revision control.
- A topic revision can be undone by a member of the [[TWikiAdminGroup]] in case needed.
