Mailing Lists
Mailman, a mailing-list management package, is heavily tested and used on many high-traffic mailing list sites to help manage and manipulate the lists themselves. Two of the strong functions that Mailman provides is a robust search engine, and the ability to browse the mailing lists online, through your browser, sorted by Subject, Author, Date, or other criteria. Mailman is used here to manage the various mailing lists that are used by projects.
