Mitmachen is a small web-interface which helps Wikipedia editors find articles which are known to need improvement. It is aimed at new editors who are looking for ways to make their first meaningful edits and do not know where to start.
Mitmachen currently works for the German-language Wikipedia only, where it will be used as part of an onboarding campaign run by Wikimedia Deutschland planned to launch in August 2018.
Mitmachen is written to run on the Toolforge Cloud-as-a-Service platform maintained by the Wikimedia Foundation. It requires direct access to some of the MediaWiki database tables of the German Wikipedia and will therefore not run on a server which does not provide such access.
To deploy Mitmachen, simply clone the Git repository to a Toolforge tool account and set up the webservice as described here.
If you found a bug, would like to contribute ideas or code, or are interested in bringing Mitmachen to another Wikipedia please head over to the Mitmachen project on Wikimedia Phabricator (or simply leave a pull request).
However, please note that there are no plans to expand Mitmachen beyond a simple web interface for a handful of database queries. For more experienced Wikipedia editors, PetScan already provides a fine-grained search functionality for articles with issues and there is a plethora of tools and bot-curated lists to find articles in need of attention.
