Help:Extension:GlobalUserPage

The GlobalUserPage extension lets you reuse the same user page across multiple wikis in a wikifarm.

Enabling your global user page
In most cases, you don't need to do anything. If a local is not showing what you desire, you may need one or more of the following steps.


 * Create your user page on the central wiki. On Wikimedia projects, your Meta user page is your global user page.


 * If the feature is disabled by default and is installed, go to Special:GlobalPreferences and enable the “Use global user page” and “Use this preference on all wikis” checkboxes.


 * If you already have a local user page on some wiki with content which you no longer want to be shown, you need to request its deletion. See Help:Deletion and undeletion for details, or contact an administrator of that wiki. Note that deleting the local user page will mean the user page will no longer appear in search results.

Where content comes from
Your global user page is generated on the central wiki, and the result is shown on local wikis. The content you see on the central wiki is what you'll see on other wikis. This means:


 * transcluding templates will use the central wiki's templates (your global user page won't use local templates);


 * transcluding special pages like  will transclude the data from the central wiki;


 * the parser function will show system messages from the central wiki;


 * magic words like will show the value from the central wiki.

Wikilinks are relative, so they'll point to the local wiki.

On Wikimedia projects, use interwiki links.

Disabling your global user page
To disable the global user page, you can use the magic word, which if present on the central user page, will prevent it from being displayed on remote wikis. This will also determine whether a link to a user page on remote wiki should be red or blue.

Controlling what content is displayed
Just like transcluding a template, you can use the and  tags to control what content is only displayed on the central site where the page exist, or globally on all sites.

You can “opt out” of global user pages by simply wrapping your central user page in tags. If the page is empty or consists only of invisible content like, it won't be shown on other wikis.

Caveats

 * Your user page might not look the same on other wikis due to differences in their site CSS. Check your page on a Right To Left wiki, e.g., ar: or he:.


 * Transclusions of special pages or parser functions like won't update as frequently as they do locally.


 * on the central wiki user page, e.g., an ICBM geohack in, will not work on local wikis.  Try  to get a page status indicator affecting only the user page on the central wiki, i.e., Meta-Wiki for most Wikimedia projects.


 * Non-content wikitext will be ignored on local wikis. This includes categories, redirects and some magic words like  and.


 * Attempts to create interlanguage links end up as ordinary User:Example links.
