That has been clearly explained in their announcement area, and even in previous posts of this thread.
There is no compulsory that you have to pay, even you can donate your credits for that.
You should either donate 15 credits or pay $15 to become a silver member for 4 months. Or you should either donate 30 credits or pay 30$ to become a gold member for 4 months.
For more detail, you can read the thread in the announcement area of the WTH forum.
