I just found this doll called SDAQR on Stardoll which has lot of free things by Stardoll Academy.
She's also a Superstar. This misteryous doll has got a lot of free items in her Beauty Parlor target Stardoll Academy, too.
What could it be? In her free things in the beauty porlor the ticket say: "Quest......"
Maybe Stardoll Academy may be something with quests and Rewards?
S.D.A.Q.R. = Star Doll Academy Quests Rewards ?
