Establish a mechanism for cross-regional/global posts
and write posts which cover interesting topics, giving perspectives from around the world, including translations
For the record: I'm assuming this is referring to a technical mechanism. As far as social mechanisms go emails to the author list are the 'mechanism' by which we now do cross-regional posts. If you meant something more specific about the social process for creating cross-regional posts please start a new suggestion with a specific idea.
No votes and IMHO it should stay that way. Any tool for this would be so complicated it would probably slow things down more than help them.
