I just signed up my wife under the default page and her upline shows as follows:
Upline 4 default 608
Upline 3 admin1 108
Upline 2 madempsey 24
Upline 1 evermore 5
As default's matrix does not appear to be full I would have expected my wife, and any other sign-ups, to be be placed in the highest available slot. Either that or the existing downline of default to be moved up to fill any holes.
Could someone that understands matrices please explain how it really works?
