Gee, free skins... wallpapers, gadgets, dreams, etc. get approved, but things that make money Stardock don't?
Stardock is a company who looks after its employees with such things as National Holidays, etc. where the Office actually closes for a short time.
Fortunately for 'most' situations there are also people who are outside the US who do not celebrate the same times/events/holidays so much of the day to day handling continues mostly as normal.
Unfortunately the process of Commercial management cannot legally be handled by anyone outside the US so delays managing Master submissions, etc are actually unavoidable, and have been ever since its inception.
By the time that every person has reached Master level they will have been members of Stardock's sites long enough to understand and appreciate this reality.
Please be patient....
