@techapj has an item to add a RSS a version of that. I guess there could be a version of this that feeds PMs for admins only.

This is now implemented via:

Okay, we now have two two independent RSS feeds for public and private posts. Public: https://meta.discourse.org/posts.rss Private (messages): https://meta.discourse.org/private-posts.rss
