From the Great Commission Movement's facebook description:
For all those involved with a church that's a part of the Great Commission Movement, including the distinct organizations Great Commission Churches (GCC), GCM Churches (GCMC), GC Latin America (GCLA), and GC Europe (GCE), all of which are part of the Great Commission Global Fellowship (GCGF).
I wasn't able to find a website for it. How long until current members start telling people "Oh, those are criticisms of GCM and GCC, but we're a member of GCMC which is completely different."
