Hi Joseph,
If you look at your profile page and select the Activity tab you will be able to see your User Statistics on the right column.
Since joining Geni you have added 841 profiles and invited 18 people to join. Currently you manage 837 profiles, the simplest explanation for the discrepancy between number of profiles added and number managed is that 4 of the invitations you sent out were accepted (you cannot manage another user's profile).
As for profiles you added being (co)managed by other people this is common due to Geni being a collaborative website, some profiles have over 1000 managers.
There is a feature where if a profile is within the Family Group of one manager but not the other managers that manager has the option to remove the other managers, but this is generally only going to affect Private profiles.
There are (at least) 40 Geni users in your tree, the software does not differentiate between users based on when they joined so being the originator has no significance.
