Just in-case anyone else needed to know, Kay's, Wamu & Hooters all report AU's.
I added my sister a month ago to all 3 of my cards and Wamu & Hooters reported on her CR about a week after.
Kays finally reorted about a week ago.
She had no score before I added her as an AU.
We pulled her scores yesterday and they are TU 722 EQ 720 EX 723.
Those 3 AU cards is all she has on her report.
Now its time for her to get her own cards.
I know alot of people dont like the AU loophole, but I'll tell you what... it does work and it will definately help my sister start her credit off on the right track.
By the time the new Fico kicks in she will have all she needs.
