57 - Set FINALPREFERENCES = WIKIWEBMASTER, PREVIEWBGIMAGE
61 - A preference is defined as: <br />`6 spaces * Set NAME = value`<br /> Example:
62 - Set WEBBGCOLOR = #FFFFC0
63 - Preferences are used as [[TWikiVariables]] by enclosing the name in percent signs. Example:
64 - When you write variable `%WEBBGCOLOR%` , it gets expanded to `%WEBBGCOLOR%` .
65 - 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.
66 - You can introduce new variables and use them in your topics and templates. There is no need to change the %WIKITOOLNAME% engine (Perl scripts).
70 - [[WebPreferences]] has preferences of the %WIKITOOLNAME%.%WEB% web.
71 - [[TWikiUsers]] has a list of user topics. User topics can have optional user preferences.
72 - [[TWikiVariables]] has a list of common `%VARIABLES%` .
73 - [[TWikiAccessControl]] explains how to restrict access by users or groups.
