Question about family tree

I finally had a hit where the person who found the bill registered to be a member. However they arent listed as a hit kid when I go to check on my Family Tree. Do they need to register a certain number for this to happen?

A user needs to enter at least 5 bills to show up in your family tree; otherwise long time users like HOGGS, Pooga and Idjit would have lists that were several hundred users long. :)

Thanks dr. Makes a lot of sense now that you mention that.
