*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 %SYSTEMWEB%.WikiCulture. Experience shows that unrestricted write access works very well because:
   * 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 %USERSWEB%.TWikiAdminGroup if necesssary.
