Patty, my first reaction to your post was "the more they have, the more they want".
Going beyond that first reaction ... your CC7 is, as of today, over 12 times larger than mine, which is almost 100% French, over 90% in Bretagne. Closest US connection is at 10 degrees, a handful of cousins emigrated to Canada around 1900, just beyond the 7th circle.
No really active WikiTreer whatsoever in my CC7, some cousins I have invited to join but who did not go further than adding a handful of profiles before giving up (too complex, too American etc etc). Closest really active WikiTreer in France and cousin is Yann Le Ny, 6th cousin once removed, at distance 12.
Our circles experience are as far as can be from each other, so I don't know how I could help the rich ones to get richer ...
[edited] : I see that your CC7 has grown by about 5,000 during the last month, twice what I have been able to add to mine in 4 years. Are you able to assess how many among those 5,000 are profiles you have created vs the ones you have brought closer by reconnection of existing branches?
