## Help on Preferences - A preference setting is defined by:
`3 or 6 spaces * Set NAME = value`
Example: - Set WEBBGCOLOR = #FFFFC0 - A preferences setting can be disabled with a # sign. Remove the # sign to enable a local customisation. Example:%BR% - #Set DENYWEBCHANGE = [[UnknownUser]] - Preferences are used as [[TWikiVariables]] by enclosing the name in percent signs. Example: - When you write variable `%WEBBGCOLOR%` , it gets expanded to `%WEBBGCOLOR%` - 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. ## Related Topics - [[TWiki.TWikiPreferences|TWiki/TWikiPreferences]], [[Main.TWikiPreferences|Main/TWikiPreferences]] - site-level preferences - [[TWikiUsers]] - list of user topics.
