[Resolved] Copying https://lists.wikimedia.org/pipermail/wikitech-ambassadors/2015-November/001290.html here, because Tech/News links here.

The welcome notification[1] shown to new users previously did not link anywhere, and just had some text which was not super useful. With the upcoming deployment of 1.27.0-wmf.7, administrators can put the page the notification should link to in the page "MediaWiki:notification-welcome-link" on your wiki. For example, on mediawiki.org, our welcome/intro page is [2], so I created [3] with the text "Special:MyLanguage/How to contribute".

This is customizable per-wiki because each wiki tends to have their welcome pages in different locations.

Original task description:

Right now the welcome notification does not have any link targets. Roan suggested that we could have an optional i18n message that would contain a page name of where the user should be sent.
