Contest Winners

I joined Inkitt last November and I signed up for both the End of Year Contest and the Dark Romance Contest. Since the deadlines have come and gone and they have posted a new contest, I was wondering when they generally announce winners of past contests. I don't expect to get anywhere close to winning any of the prizes but I was curious to know which works had won. How does that happen? It's like the contest ended and I heard/saw nothing else about them. How long does it generally take for them to announce winners?
