How do the Independent Catholics organize?

This is more a request than a blog post, and I’m reaching out to people in the Independent Catholic or Independent Sacramental movements, and particularly those in structured communities, like parishes or worship groups.

How do you organize your groups? How do you work between groups? In what way does your group function like “establishment” churches and which way does it not?

I would appreciate any feedback, and I think we generally have much to learn as religious institutions have their privileged place challenged.
