Wikimedia-wide issues
Wikipedia and its sister projects are organized in the Wikimedia Foundation. Wikimedia-wide issues can be discussed either on Meta-Wiki or on the foundation-l mailing list. If you ever want to bring an issue to the attention of the entire Wikimedia community, the foundation list is the best medium for doing so. But please use project-specific mailing lists for issues which concern just one project. You don't have to subscribe to keep up to date on current community happenings - on Meta provides a weekly digest. On Wikipedia, to keep up with current events, visit the Wikipedia:Community Portal.
