View of all newsletters on a wiki

The Newsletter extension provides a catalog of newsletters registered in a given wiki, an easy way for publishers to announce new issues, and an easy way for users to subscribe/unsubscribe and be notified via web or email when new issues are announced. A "newsletter" is defined as a publication that has a name, a wiki home page, and a single or central wiki page for each issue or edition. For user documentation, check Help:Extension:Newsletter .

Subscribe to Newsletter², the newsletter about the Newsletter extension. Announcements, calls for feedback, and some dog food too.

You can test the extension in our vanilla installation or at test.wikipedia.org. We welcome feedback and contributions!

This extension was created in 2013, then modified heavily as part of a Google Summer of Code 2015 project. Its development team is formed mostly by volunteers, and we welcome new contributors. Our goal is to deploy this extension in Wikimedia. Check the ongoing work in our Phabricator workboard.

After a lot of additional work by other contributors, it was made available to Wikimedia users on July 2017.
