---+ TWiki Groups

These groups can be used to define fine grained %TWIKIWEB%.TWikiAccessControl in <nop>%WIKITOOLNAME%:

%SEARCH{"GROUP" topic="*Group" casesensitive="on" nosummary="on" nosearch="on" noheader="on" nototal="on" format="   * $topic$n      * <font size=\"-1\">Members: $pattern(.*   \* Set GROUP =([^\n]*).*)</font>"}%

     <input type="hidden" name="templatetopic" value="TWikiGroupTemplate"/>
     <input type="hidden" name="topicparent" value="%TOPIC%"/>
     <input type="hidden" name="onlywikiname" value="on" />
     <input type="hidden" name="onlynewtopic" value="on" />
      * %ICON{"warning"}% __Note:__ A group topic name must be a %TWIKIWEB%.WikiWord and __must__ end in =...Group=. New topics are based on TWikiGroupTemplate
</form>

*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 %TWIKIWEB%.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 %MAINWEB%.TWikiAdminGroup if necesssary.
