## %WEB% Web Preferences
The following settings are **_web preferences_** of the [[%WEB%|WEB/WebHome]] web. These preferences overwrite the **_site-level preferences_** in [[TWikiPreferences]], and can be overwritten by **_user preferences_** (your personal topic, i.e. [[TWikiGuest]] in the %WIKITOOLNAME%.Main web)
**_Preferences:_**
- List of topics of the %WIKITOOLNAME%.%WEB% web:
- Set WEBTOPICLIST = [[Users|Main/TWikiUsers]] | [[Groups|Main/TWikiGroups]] | [[Offices|Main/OfficeLocations]] | [[Changes|Main/WebChanges]] | [[Index|Main/WebIndex]] | [[Search|Main/WebSearch]] | Go
- Web specific background color: (Pick a lighter one of the [[StandardColors]])
- Set WEBBGCOLOR = #FFFFC0
- List this web in the [[SiteMap]]:
- If yes, Set SITEMAPLIST = `on`, and add the "what" and "use to..." description for the site map. Make sure to list only links that include the name of the web, e.g. %WEB%.Topic links.
- Set SITEMAPLIST = on
- Set SITEMAPWHAT = Welcome to %WIKITOOLNAME%... [[Users|WEB/TWikiUsers]], [[Groups|WEB/TWikiGroups]], [[Offices|WEB/OfficeLocations]] - tour this expandable virtual workspace.
- Set SITEMAPUSETO = ...get a first-hand feel for TWiki possibilities.
- Exclude web from a `web="all"` search: (Set to `on` for hidden webs)
- Set NOSEARCHALL =
- Default template for new topics and form(s) for this web:
- [[WebTopicEditTemplate]]: Default template for new topics in this web. (Site-level is used if topic does not exist)
- [[TWiki.WebTopicEditTemplate|TWiki/WebTopicEditTemplate]]: Site-level default template
- [[TWikiForms]]: How to enable form(s)
- Set WEBFORMS =
- Users or groups who **_are not_** / **_are_** allowed to **_view_** / **_change_** / **_rename_** topics in the %WEB% web: (See [[TWikiAccessControl]])
- Set DENYWEBVIEW =
- Set ALLOWWEBVIEW =
- Set DENYWEBCHANGE =
- Set ALLOWWEBCHANGE =
- Set DENYWEBRENAME =
- Set ALLOWWEBRENAME =
- Users or groups allowed to change or rename this %TOPIC% topic: (I.e. [[TWikiAdminGroup]])
- Set ALLOWTOPICCHANGE =
- Set ALLOWTOPICRENAME =
- Web preferences that are **not** allowed to be overridden by user preferences:
- Set FINALPREFERENCES = WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME
**_Notes:_**
- A preference is defined as: `6 spaces * Set NAME = value` Example:
- Set WEBBGCOLOR = #FFFFC0
- 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 new preferences variables and use them in your topics and templates. There is no need to change the %WIKITOOLNAME% engine (Perl scripts).
