Mediawiki Newsletter Extensionhttps://www.mediawiki.org/wiki/Extension:Newsletter
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.
