The core plugin pilots, health check and post by email, now have developer mailing lists. You can sign up for the mailing lists if you’re interested in being involved with the development of either of these plugins. Note: these lists are NOT meant for discussion of the core plugin concept, just for the development of the actual plugins, so please keep on topic to minimize noise. The idea is that as we move forward in figuring out core plugins as a concept, each one will have a mailing list for developers, and one for notifications. I’ve heard talk about having notification lists for all plugins in the repo, too, but that’s a different topic. :)

In the meantime, here’s where the core plugin dev lists can be accessed.
