Users or groups who are not / are allowed to view / change / rename topics in the Deployment web: (See TWikiAccessControl). Remove the # to enable any of these settings. Remember that an empty setting is a valid setting; setting DENYWEBVIEW to nothing means that anyone can view the web.
Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
When you write variable %WEBBGCOLOR% , it gets expanded to #FFF0CE
The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
You can introduce your own preferences variables and use them in your topics and templates.
