T41401 (Bug 39401) asks to add calls-to-action to invite to the Teahouse. The Teahouse is a particular page on the English Wikipedia. This must not be in the core AFT software. It must be usable on all wikis and languages.
It's perfectly fine to have a link to a page which is like the Teahouse. Wikipedias in many languages have similar pages. But they have different names and URLs, so this must be generic and it configurable by the site's users (probably administrators) and not in the extension's source code or in LocalSettings.
