The congregation I serve is an established (60 yrs. old) suburban/urban CRC that increasingly is captivated by a missional identity and desires to see that identity lived out in our neighborhoods, communities, and network of relationships that our members are part of. Our leadership is at the very early stages of exploring the concept of "missional communities". I have talked to a couple of leaders in the CRC who are in process of implementing MC's in their setting, but each setting is quite different from ours in that they are younger churches / church plants with a considerably younger demographic than our congregation. Our church has a fairly even spread of youth, young family, middle age, seniors.
I'd love to learn from or learn with leaders that have navigated (or are navigating!, or even just considering) the significant shift from a traditional CRC structure / culture, to one that employs the "missional communities" model. The model that I am refering to flows mainly out of the writings of Mike Breen and company with 3DM.
