mailing lists! A mailing list is a shared address for a list of recipients. Anyone subscribed to the list can send e-mail to that address and thereby reach all other subscribers. This is a convenient way to discuss complex issues with multiple people. There is a WikiEN-l list which is used for discussing policies and current issues related to the English Wikipedia, and there is Wikipedia-l for language-independent discussions. If you want to help developing MediaWiki, join Wikitech-l and share your ideas. For a complete list see m:Mailing lists
